Franny K. Stein is not your average girl—she's a mad scientist. She prefers poison ivy to daisies, and when Franny jumps rope, she uses her pet snake. The kids in Franny's class think she's weird, wacky, and just plain creepy. Tired of being stared at, Franny decides to attempt her most dangerous experiment yet—she's going to fit in. but when a giant Monstrous Fiend attacks the class, everyone knows it's up to a mad scientist to save the day. But has Franny lost her creepy, crawly ways?

Franny's mom says every mad scientist needs a lab assistant. So for Valentine's Day Franny gets just that—a Lab assistant. Except Igor isn't a pure Lab. He's also part poodle, part Chihuahua, part beagle, part spaniel, part shepherd—and all thumbs. Franny is fuming. She doesn't even need an assistant. What's she supposed to do with a good-for-nothing one like Igor? And things get even worse when a giant, fifty-foot, arrow-shooting cupid starts causing trouble all over town. Franny knows it's up to her—and only her—to save the day. Or is it?

There's nothing better than being a mad scientist—at least according to Franny. So she's making in her mission to help her classmates discover their own inner mad scientists. All Franny needs for her latest experiment is a few volunteers, a half-completed two-headed robot, and an invisibility potion. Only this experiment just might prove to be Franny's most difficult. What do you do when your classmates don't know anything about mad science and there's a doubly dumb robot running amok to prove it?

Franny K. Stein didn't think the time would ever come when someone would realize what the K in her name stood for. And she REALLY didn't think that same someone would say her middle name in front of the whole school! But that's what happened at the Science Fair award ceremony, and all the kids and teachers burst out laughing. So Franny does what any respectable mad scientist would do—she goes back in time to change her name. However, things don't always turn out as calculated, and Franny ends up having to face her teenage self in a warped, fourth-dimensional, kid-versus-teen, good-versus-evil, Franny-versus-Franny battle of the minds!

Franny's faithful lab assistant, Igor, has swallowed a doomsday device that is ready to go off at any moment! For any regular scientist, there is only one way to get the device out—um...make that two ways. But Franny K. Stein is no ordinary scientist, so she concocts her own way to get the device back and save her friend. With her miniaturization machine, Franny shrinks herself to the size of a pin and goes on a field trip like no other...through the body of a ticking time-dog! Fasten your seatbelts, it's going to be a bumpy ride!

Being a mad scientist in the modern world is very hard work. With so much that needs to be done in such a short period of time, multitasking can get way out of hand. Franny needs some additional help. But for Franny there is only one person in the world she trusts to help her with her experiments—herself. So she acquires assistance the mad-scientist way, by building a few real, live, steel-plated Franbots. Spotlight editions are printed on high-quality paper and with reinforced library bindings specifically printed for the library market. Grades 3-6.

Goosebumps and Bill Nye the Science Guy fans, meet Franny! Franny K. Stein, Mad Scientist, has always had her eye on world domination, and she has to start somewhere...like her class elections!
