The Invasion
1996
Sometimes weird things happen to people. Ask Jake. He may tell you about the night he and his friends saw the strange light in the sky. He may even tell you about what happened when they realized the "light" was only a plane—from another planet. Here's where Jake's story gets a little weird. It's where they're told that the human race is under attack—and given the chance to fight back.
Now Jake, Rachel, Cassie, Tobias, and Marco have the power to morph into any animal they choose. And they must use that power to outsmart an evil that is greater than anything the world has ever seen...
#2
The Visitor
1996
If someone told you Earth was under a silent attack, there's a good chance you'd think they were pretty strange. If that same person said Earth's only means of defense depends on the actions and powers of five kids, you'd probably start to look for a quick exit. Guess what? It's all true.
Rachel and her friends knew they were in for some pretty strange stuff from the very beginning. How often do you run into a dying alien who gives you the power to morph into any animal you touch? But that was before they knew what they would be up against. Now they know. And they know what they have to do. Before it's too late...
#3
The Encounter
1996
When Tobias, Jake, Rachel, Marco, and Cassie were given the ability to morph, they were also given one very important warning: Never stay in a morph for more than two hours. It seemed a small price to pay, since the kids know that humans everywhere are being forced to let slimy, spineless creatures creep into their brains. And the only way the kids can fight back is not to be human.
But Tobias stayed in his morph too long. And now he's a hawk—with a boy's mind—forever. Tobias knows they can't give up. That they all made a promise. So now it's four kids and a hawk against a force that's determined to destroy them. Or die trying...
#4
The Message
1996
Unable to ignore the strange dreams that she and her friends have experienced since they developed morphing powers, Cassie wonders if a dream that draws her to the sea is a cry for help or a trap. Original.
#5
The Predator
1996
Marco never wanted to be an Animorph. He never wanted the ability to change into any animal he touches. He just wants to chill. Whatever happens, happens.
Jake, Rachel, Cassie, and Tobias know why Marco feels the way he does. He's worried about his dad—the only family Marco has left. And if anything happens to him, his father will be all alone.
But something is about to change Marco's mind. It seems the Yeerks have a little surprise waiting for him. And it's definitely not nice.
Now Marco has a reason to fight...
#6
The Capture
1997
It was really bad when Jake found out his older brother was one of them. It was even worse when Tobias stayed in his morph too long. But nothing compares to the horror the Animorphs are about to face. Nothing.
Jake, Rachel, Tobias, Cassie and Marco have a feeling they know where the Yeerks' new base is located. And they've even figured out how to get in—how many people notice a few flies on the wall? But they never figured they might get caught. Or that Jake could fall into the Yeerk pool. That Jake could become a human controller.
A Yeerk.
The enemy.
#7
The Stranger
1997
Okay. Rachel and the other Animorphs have finally found the new entrance to the Yeerk pool. They've even figured out a way to sneak in. The infamous roach morph. But they didn't count on roaches being a Taxxon delicacy. This time escape doesn't look so good.
And then everything stops. Everything. The feasting Taxxon, the human-Controllers, the Hork-Bajir. Time. Now Rachel, Cassie, Marco, Jake, Tobias, and Ax are in for their wildest trip ever. They're going to get the chance to decide whether they want to stay on Earth and fight the Yeerks. Or go to another planet. And the guy giving them the choice says he can save them. Now all they have to do is make the choice...
#7.5
The Andalite's Gift
1997
We never should have done it. But we needed a break. You know, some time off from the superhero stuff. A chance to act like normal kids. Well—as normal as four kids who can morph, a hawk, and an alien can be. Everything should have been cool.
Now Rachel is missing. And there's this . . . this thing that's after us. But it's not up to me to tell the whole story. Tobias, Cassie, Marco, and Ax were there, too. Even Rachel has some info to add. So go ahead and check this out. And remember not to tell anyone what we're about to tell you. It could mean the difference between life and death. Or worse...
#8
The Alien
1997
What would you do if you were the only alien trapped on a strange planet? Probably freak out, right? But as an Andalite warrior-cadet, Ax has to be pretty cool about stuff like that. He's been hanging with the Animorphs ever since the Dome ship was destroyed by the Yeerks and his brother, Prince Elfangor, was destroyed by Visser Three.
Life on Earth is pretty different for Ax. But there is one thing he, Cassie, Marco, Jake, Rachel, and Tobias have in common. Something that one alien, four kids and a hawk know they have to do: stop the Yeerks...
#9
The Secret
1997
There's something pretty weird going on in the woods behind Cassie's house. The place where Ax and Tobias call home. It seems the Yeerks have figured out one very important thing: Andalites cannot survive without a feeding ground. Visser Three knows the "Andalite bandits" don't feed where he does, so there can only be one other place.
Now Cassie, Marco, Jake, Rachel, Tobias, and Ax have to figure out a way to stop a bogus logging camp. Because if Visser Three finds Ax in the woods, nothing will stop him from finding the Animorphs...
#10
The Android
1997
When Marco runs into his old friend Erek he doesn't think too much of it. He's got a couple of more important things to do. Like helping to save the world. But then Marco finds out Erek's been hanging with some of the kids at The Sharing. And he starts to think that something just a little weird is going on.
So Marco, Jake, and Ax decide to morph and check old Erek out. Just to see if he's been infested with a Yeerk. The good news is that Erek's not a human-Controller. The bad news is that Erek's not even human...
#11
The Forgotten
1997
There's been an accident. Someone crash-landed a Yeerk Bug fighter. And the Yeerks have been trying to cover it up—quickly. But not before Tobias spots it. So the Animorphs and Ax decide to steal the ship to show the world that Earth has been invaded.
That's when things go terribly wrong. Before they know it, Jake, the other Animorphs, and Ax find themselves in another place. Another time. And there's no way home...
#12
The Reaction
1997
Rachel's got some pretty strange stuff happening. She can't control her morphing. One minute, she's doing homework. The next, she's morphing a full-grown crocodile, and—without returning to human form—she becomes an elephant. That's when the floor gives way and Rachel finds herself looking up at what used to be the kitchen ceiling.
What's going on? No one's sure, but Rachel and the other Animorphs have to figure it out—quickly. Because if someone sees Rachel's out-of-control morphing, the other Animorphs and Ax are in some serious trouble...
#12.5
The Andalite Chronicles
1997
His name is Elfangor-Sirinial-Shamtul.
An Andalite war-prince. The one who gave five young humans the ability to morph into any animal they touch. They are still out there, fighting an evil so powerful there isn't a moment that goes by when they can actually feel safe. Their story continues.
But this is how it all began.
The story that came before Animorphs . . .
#13
The Change
1997
Tobias has pretty much gotten used to his life. He's a red-tailed hawk with the mind of a kid. It was weird when he first got trapped in morph. But now it's almost okay. After all, how many kids actually get the chance to fly?
Now Tobias is about to make a very special choice. A choice that the other Animorphs and Ax know nothing about. And it could mean the difference between being a hawk. . . and being human...
#14
The Unknown
1998
There's a new rumor in town. Someone has discovered an item that proves life on other planets exists. And they've been hiding it on a base called Zone 91. The Most Secret Place On Earth.
Cassie, the other Animorphs, and Ax already know about life on other planets. Too well. They also realize the Yeerks will try to access Zone 91. To find out if what's there will threaten their mission. So the Animorphs decide to pay Zone 91 and the Yeerks a little visit. But what they discover is not at all what they expect...
#15
The Escape
1998
Almost nothing could be as bad as finding out your mother is Visser One. The most powerful of all Vissers. The leader of the Yeerk invasion of Earth. But it happened to Marco. And even though he's been handling it pretty well, he knew there'd come a time when he'd have to face her again. Knowing that the Yeerk in her brain had taken his mother away.
So when Marco, the other Animorphs, and Ax discover that Visser One is overseeing a secret underwater project, they know they have to check it out. But Marco's not sure if this is a battle he'll be able to fight....
#16
The Warning
1998
Jake's made a pretty amazing discovery. It seems like there may be other people who know about the invasion. Others who know about the Yeerks. Jake finds a Web site devoted to the Yeerks. And Jake, the other Animorphs, and Ax aren't sure it's too good to be true.
But if they try to investigate the site and it's a trap, there's no way the Yeerks won't find out who they are. If they don't check it out, they'll never know if they're the only ones fighting. Whatever Jake and the others decide to do, they've got to move quickly, because Visser Three isn't the only one dying to meet them...
#17
The Underground
1998
What's tasty, good for you, and only takes sixty seconds to make? Oatmeal. And it's making the Yeerks more than a little crazy. Now Rachel, the other Animorphs, and Ax have a new weapon against the Yeerks. Sounds good, right?
Wrong. Because it means another trip to the Yeerk pool. And the possibility of running into Visser Three. And of not being able to get back up to the surface. The Animorphs and Ax have taken chances before and been very lucky. But this time their luck may be about to run out...
#18
The Decision
1998
Ax and the Animorphs are about to have a huge problem. It starts when they decide to morph mosquitoes in order to slip by some unsuspecting Yeerks. It ends with them stuck in Zero-space with no idea how they got there, no way to get back to Earth . . . and no oxygen.
Luckily, an Andalite scout ship finds them before it's too late. But now Ax is finally with his own people. And he doesn't know if he ever wants to go back to Earth...
#18.5
In the Time of Dinosaurs
1998
We could blame everything that happened on Marco. He was the one who heard about the downed submarine. He was the one who thought we should check it out. And everyone knows that if Marco's up to a challenge, I'm definitely there.
Everything was going fine. Until the explosion. An explosion that blows us millions of years back in time. Back to the age of dinosaurs. Now Tobias, Cassie, Marco, Ax, Jake and I are fighting for our lives with every step we take. But that's not our biggest problem. Our biggest problem is we have no idea how to get back to our own time...
#19
The Departure
1998
Cassie's had it. After the last mission, she realizes she's getting tired of missions. Tired of battles. Tired of being an Animorph. She decides that she just can't do it anymore. So she quits.
But the war for her planet isn't so easy to quit. It seems a human-Controller named Karen followed Cassie after the last run-in with the Yeerks, and she knows Cassie has the ability to morph. If she exposes Cassie, it's all over. No more Cassie. No more Animorphs. No more planet Earth.
#20
The Discovery
1998
The blue box Elfangor used to create the Animorphs has been found by a kid named David. David has no idea what he has—or what it can do. But Marco does. And when he sees David with it, he knows the Animorphs have to get that box. At any cost.
But what should have been a simple plan ends up going horribly wrong. And David is on the run with the Animorphs and Ax. Now they have only two choices: turn David over to the Yeerks. Or make him the sixth Animorph...
#21
The Threat
1998
There is a new Animorph. And he's arrived just in time, because the Yeerks are preparing their biggest takeover ever. The ultimate target: the world's most powerful leaders gathered together in one place. What better way to get into the minds of humans? Literally.
At first, David joins the fight with a vengeance. But there is definitely something wrong. Because he's starting to break the rules. Taking risks that could get them all captured. Or killed. The Animorphs don't know what to do. Because there was a time when the Yeerks were their greatest enemy. That's about to change...
#22
The Solution
1998
David, the newest Animorph, is not what he appears. His need to control the other Animorphs and Ax is all he thinks about. And the things he does are starting to break up the group.
Rachel and the others know that time is running out. The newest battle against the Yeerks is the most important one yet. And it's not one that will wait. Winning this fight could mean slowing down the invasion. But no one knows what to do with David. Because the newest Animorph is more than just a little problem. He's deadly...
#22.5
The Hork-Bajir Chronicles
1998
Dak Hamee, born into the Hork-Bajir tribe, is something special from the start. "Strange," says his mother. "A seer," says the Old One, Tila Fashat. "A seer is one who is born to show a new way. Many, many seasons pass, then our father, the Deep, and our mother, the Sky, say, 'Send a seer to the people. The people have need.' And so one is born who is different." When strange and different Dak meets Aldrea, the clever Andalite daughter of Prince Seerow, they learn together of the dangerous plot of the Yeerks, and of Esplin 9466, who will stop at nothing to build his empire. Learn more about Prince Seerow's Kindness, find out how Andalites kiss, and plumb the mysteries of the Deep in this suspense-filled story of good, evil, and interspecies love. (Ages 9 to 12)
#23
The Pretender
1998
Someone's looking for Tobias. Someone who says she's his long-lost cousin. Tobias isn't sure the person is telling the truth. But she's really nice, and knows a lot about him. And what she tells Tobias definitely gets his attention.
It seems a lawyer has discovered Tobias' father's last will and testament. So, Tobias needs to attend the reading. His "cousin" even offers to go along. But something just doesn't feel quite right. That's when Tobias, the other Animorphs, and Ax decide to do a little checking on this "cousin". And what they discover will change the rest of Tobias' life....
#24
The Suspicion
1998
Cassie, the other Animorphs, and Ax have a few little problems. A few very little problems. Actually, the problems call themselves Helmacrons. They're less than an inch tall, and they're pretty upset at Cassie. They believe she stole their ship. Cassie thought it was just a toy, and gave it to charity. Now the Helmacrons want it back.
So the Animorphs and Ax have a new dilemma. Because the Helmacrons have their own secret weapon: They can shrink other beings down to their size. And, if they don't get their ship back soon, everyone on the planet is in for a little surprise...
#25
The Extreme
1999

#26
The Attack
1999
The Animorphs have met the Ellimist. He "helped" to save the kids when they were about to be eaten by a Taxxon. He "helped" to free two Hork-Bajir and restored Tobias' morphing ability. But, even though the Ellimist has enormous power, he is not all-powerful. He has an enemy. The Crayak.
So, the Crayak and the Ellimist decide that a battle will prove their ultimate power. But they don't intend to fight each other. The Ellimist will choose the Animorphs, Ax, and Erek, the Chee; the Crayak will choose his own army. If the Animorphs lose they will be erased from the universe altogether. And there'll be no one left to fight the Yeerks...
#27
The Exposed
1999
The Animorphs and Ax have one true ally in their battle against the Yeerks: the Chee. So, when they discover that the Chee—including their friend, Erek—are in trouble, they have no choice but to help.
But the Chee's problem is much deeper than anything the kids could have imagined. It's hidden in the ocean. So far down that no human has ever traveled there—and survived. And the Animorphs realize what will happen if Visser Three discovers the valuable secrets of the Chee. One of which is the Animorphs...
#28
The Experiment
1999
The Yeerks have decided to try a little experiment. They've decided that if they can develop a way to make people more "willing" to be infested, they can speed up Earth's invasion. So, the Yeerks try to invent a substance that will take away the human ability to make a decision. A substance that will eliminate free will.
Now the Animorphs and Ax are not only faced with trying to slow down the Yeerks' invasion, but they also have to put an end to the genetic testing on a small group of humans. This time there's only one chance to stop the Yeerks. And if anything goes wrong, it's all over...
#29
The Sickness
1999
Something is very wrong with Ax. He's sick. And the Animorphs don't know what to do about it. They can't take him to a hospital. They don't know how to contact the Andalite home world. And Ax is dying.
Cassie and the other Animorphs come up with a plan. But it involves finding a new way into the Yeerk pool. There's just one problem: Jake, Rachel, Tobias, and Marco come down with Ax's sickness. And now, for the first time, Cassie is on her own...
#29.5
Elfangor's Secret
1999
We found out who Visser Four is. And he has found the Time Matrix, the machine Elfangor had hidden in the abandoned construction site. The same place we met him on a night none of us will ever forget. Especially me. Now Visser Four has the Matrix, and he plans to use it to become Visser One.But Jake, Rachel, Cassie, Marco, Ax and I can't let that happen. We can't let him alter time so that the Yeerks will win the invasion. So we're prepared to make the ultimate sacrifice. Eventually, one of us will lose this fight...
#30
The Reunion
1999
Marco's mom is back. But she's not Visser One anymore. Marco's not even sure if she's still a Controller. But he's determined to find out. No matter what it takes. No matter what might happen. Marco wants his mom back.
Jake, the other Animorphs, and Ax realize that Marco is under some serious stress. And that the situation with his mom could very well jeopardize everything they've worked for. Now they also have to wonder if Marco will be the one to give away the secret of the Animorphs...
#31
The Conspiracy
1999
Jake's great-grandfather has died. It blows the family away—especially Jake's mom. So Jake's parents decide they should all travel to the great-grandfather's home to help with any arrangements. In another state. For three or four days.
This is a very big problem for Jake's brother, Tom. He can't be away from the Yeerk pool for that long. So Tom refuses to go—and his father insists. But Tom's Yeerk will do anything to survive. Including making his father less of a problem.
Now Jake, the other Animorphs, and Ax have to find a way to protect his father without Tom discovering their secret. And without having to choose between his father's life. . . and Tom's.
#32
The Separation
1999
Rachel is falling apart. Literally. Her newest morph has the ability to regenerate its limbs, but when Rachel demorphs there's a lot more Rachel than when she started out. One more Rachel, to be exact. Rachel is an okay person to have around. But two could be considered overkill. Especially two Rachels with completely opposite personalities: one is pathetically weak; one is super strong and super nasty.
Now the Animorphs have to figure out a way to put Rachel back together again. Because if it's up to the "twins," Rachel the weak will surrender to Visser Three. Rachel the super bold will try to single-handedly take him down. And twice the trouble may be twice as much as the other Animorphs and Ax can handle...
#33
The Illusion
1999
Tobias, the other Animorphs, and Ax already have a few problems: saving the world, keeping their identities secret, finishing their homework. Now they have one more thing to add to the list. The Yeerks have discovered a way to cause a person to demorph. And with this new device Visser Three plans on capturing "the Andalite bandits."
Now what? The Animorphs and Ax realize they have to get rid of the device—or be captured by the Yeerks. And the risk of getting caught is very high. That's when Tobias comes up with the only possible plan. Someone has to acquire Ax...
#34
The Prophecy
1999
There is a chance for the free Hork-Bajir on Earth to help start a rebellion against the Yeerks on the Hork-Bajir homeworld. And they've learned from the last surviving Arn—the race that created the Hork-Bajir—that Aldrea, daughter of Prince Seerow, knew the location of a stolen Yeerk vessel packed with weapons.
Unfortunately, the only way to recover the ship is to ask Aldrea herself—and she's dead. But the Arn has Aldrea's persona stored. And Cassie, Rachel, or Toby Hamee are the closest match. The only problem is that once Aldrea gets into one of their minds, she may not want to come out...
#35
The Proposal
1999
Marco already knows he has a few problems: the constant battle with the Yeerks; finding out his mother was infested . . . and is now Visser One. The leader of the Yeerk invasion of Earth. But things are about to get even weirder. Marco's father is thinking of getting married again.
Meanwhile, the Animorphs and Ax have other things to worry about. It seems the Yeerks are trying harder than ever to get people into The Sharing. Now the kids have to find a way to slow down recruitment. But Marco's personal stress is causing him to morph into creatures that don't exist. Creatures the Yeerks are sure to notice . . . and attack...
#35.5
Visser
1999
In an hour or so, once I was out of sight of land, I would lower my sails and wait for a Bug fighter to come lift me off the deck. The engine backwash of the Bug fighter would capsize the boat. Or I might put the Taxxon pilot to the test and see if he could ram the low-slung boat. That would puzzle the humans.
Either way, my body would never be found...
My time of lying low was over...
I would spearhead the invasion of Earth. I would take charge of our greatest conquest. I would stand alone atop the Yeerk military hierarchy.
I was to become Visser One.
From the Hardcover edition
#36
The Mutation
1999
Visser Three is still trying to find a way to reach the Pemalite ship. The ship that was hidden thousands of feet below the ocean's surface. A ship containing technology so advanced that it is superior to anything even the Andalites have built. And this time, the visser plans to find the ship so he can use the power to complete Earth's invasion.
Jake, the other Animorphs, and Ax acquire additional deep-sea morphs in order to stop the visser's plan. But while trying to destroy the Yeerk ship, the kids make a startling discovery: an underwater civilization. Have the kids discovered Atlantis . . . or is it just another trap?
#37
The Weakness
2000
When Jake has to leave town for a family thing, the other Animorphs and Ax figure life will pretty much be normal until he gets back. But when Tobias discovers Visser Three's newest feeding place, the kids decide they have to check it out.
But there's no assigned leader. Now Rachel, Tobias, Cassie, Marco, and Ax have another problem: Who will be the best one for the job? Because being in charge isn't just guts and glory. It's about making decisions that will mean the difference between life . . . and death.
#38
The Arrival
2000
Andalites have finally arrived on Earth. The Animorphs and Ax now have allies willing to fight against the Yeerk invasion. But there are only four Andalites. Not nearly enough to defeat thousands of Yeerks. Not enough to stop humans from being infested.
So, everyone agrees that the battle must continue. But the Andalites don't want to fight alongside humans. They feel their skills will be less than adequate. And they demand that Ax choose a side. Will Ax stay with his friends . . . or stand with his people?
#39
The Hidden
2000
The Yeerks have discovered and repaired a damaged Helmacron ship. They know of its morph-seeking capabilities, and they plan to use the ship to capture the "Andalite bandits." And to find Elfangor's blue cube. The one that gave the kids the ability to morph.
Cassie, the other Animorphs, and Ax are in a pretty bad situation because they can't leave the cube in one place, they can't morph without being discovered, and they have to keep moving. It looks like this may be a battle the Visser can't lose...
#40
The Other
2000
Ax and the Animorphs have always believed he was the only non-infested Andalite on Earth. That he alone survived the terrible battle between his people and the Yeerks.
Until now.
There were other survivors. Other Andalites. And they're here on Earth. Trying to keep a low profile. Trying to find a way to defeat Visser Three. Trying—like Ax and the Animorphs—to stay alive until help finally comes.
If help finally comes . . .
#40.5
Back to Before
2000
What would you do if you had the opportunity to change your life? Not just where you live or who you hang out with, but your past, present, and future? Sounds like it might be pretty cool, right? Well, that's what Jake thought. He thought it might be easier if the Animorphs had never existed. If they'd never met Elfangor. If they all had the chance to be "normal" kids.
Jake gets his wish.
But things aren't quite as simple as they seem. Just because the Animorphs no longer exist doesn't mean the Yeerks no longer exist. Except now Jake, Rachel, Tobias, Cassie, and Marco can't morph. They don't even know the Yeerks are out there. And it's not such a wonderful life...
#41
The Familiar
2000
Jake is just a normal kid. Well, as normal as possible considering he can morph animals, and he's in a war against parasitic aliens. But as unbelievable as it sounds, something even stranger has happened. One morning Jake wakes up, and he's twenty-five years old.
Okay. Maybe it's some kind of weird hallucination. Maybe it's a nightmare. Or maybe Jake's just lost it for a while and misplaced a few years. And there's another problem. The world Jake-the-kid went to sleep in has changed. It's ruled by the Yeerks. Jake has to find out if the other Animorphs and Ax are still around. Still somehow fighting. Or if he's really on his own...
#42
The Journey
2000
Sometimes your worst problems are the ones you can't actually see. Like the Helmacrons. These less-than-an-inch-high aliens are back, and they want the morphing cube more than ever. Obviously, Rachel, the other Animorphs, and Ax can't let them take the cube. But when Rachel tries to stop the Helmacrons from stealing it, Marco gets in the way and ends up with tiny aliens, well, up his nose.
Rachel and the others can't let the Helmacrons stay inside Marco's head. They're armed, and could cause serious damage. So the Animorphs and Ax come up with a plan to evict the Helamcrons from their new residence. But it involves a shrinking ray and the obvious: Marco's nose...
#43
The Test
2000
Tobias, the other Animorphs, and Ax have seen things so bizarre that no sane person would believe their story. No one would believe that aliens have taken over Earth, and are in the process of infesting as many humans as possible. No one could believe the battles and missions and losses these six kids have had to deal with. And it's not over yet.
Tobias has been captured by the same human-Controller that nearly tortured him to death once before. She claims that now she's a part of the Yeerk peace movement. That she just needs a favor. Tobias isn't sure what to believe, but he knows that if the Animorphs and Ax don't find him soon, what he believes won't matter anymore...
#44
The Unexpected
2000
The Animorphs have been split up before. And they've had to fight battles without one another. But this time is very different. Not only is Cassie totally alone. She's managed to find herself in Australia. In the rural Outback. The other Animorphs and Ax don't even know she's there.
Cassie doesn't have any idea where she's going, or if she can even survive the rugged terrain. But she does know she has to get to a town or village and contact her family and friends. Because she just realized that there's someone else who is also new to the Outback.
Visser Three.
#45
The Revelation
2000
Things were already really weird. Fighting aliens. Battling to save Earth. And still trying to be normal. Marco, the other Animorphs, and Ax are almost used to it. Almost. But things are changing. The Yeerk invasion of Earth started out passively. Secretly. But now, everything seems to be stepped up. Even Marco's father is talking about some top secret project at his job. Something about developing Zero-space . . .
Marco doesn't even know whether his father is a Controller. But he does know he's not going to let the Yeerks win this one. They've already got his mother. And Marco will do anything it takes to save his father. Anything . . .
#46
The Deception
2000
The Animorphs and Ax have managed to contact the Andalite home world. But the battle is far from over. Visser Two has arrived to Earth, and he's not happy about the state of things. He decides the best way to take over Earth is to have the humans destroy the people and the land the Yeerks don't need. He decides to start World War III.
Ax and his friends know that Visser Two means business and there will probably only be two ways to keep him from destroying everything they know: Find a way to stop the war. Or find a way to stop him. . . forever...
#47
The Resistance
2000
The Animorphs and Ax have to make the most important decision they've ever had to make: Do they continue to fight the Yeerks in secret, or is it time to let everyone know there is a resistance? That the Animorphs exist. And that Earth does stand a small chance against the invasion.
Jake knows that either choice is a major one. Not one that some kid should be responsible for. But he's getting tired of the pressure. So, even though he realizes that other Animorphs need him to be strong, he doesn't feel that way. In fact, he feels just the opposite. And Jake knows if he starts to lose it the Animorphs are done...

The Ellimist Chronicles
2000
Librarian's note: There is an Alternate Cover Edition for this edition of this book here.
He is called the Ellimist. A being with the ability to alter space and time. A being with a power that will never be fully understood. He is the reason Elfangor came to Earth. He is the reason the Earth now has a fighting chance. And though his actions never seem quite right or wrong, you can be certain they are never, ever what anyone expects.
This is the beginning and the middle of the story. A story that needs to be told in order to understand what might happen to the future. The future of the Animorphs. The future of humanity. The future of Earth.
He is called the Ellimist. And this is his story . . .

When Tobias, the other Animorphs, and Ax realize that the Yeerks are about to find them, it's by accident. But that doesn't make the discovery any less serious. Because in war, one side wins. And one side loses...
