Contact Front
2020
Go to war or go to jail. For small-time street hustler Cam Alvarez, the choice is simple. He has no family, no friends, no place in the world…nothing to lose. When his latest con results in the death of a cartel hitman, Cam opts to join the Marines and leave Earth to fight a vicious alien enemy. Drafted into the Marine Drop-Troopers, Cam discovers there’s one thing he’s even better at than running street-con games, and that’s killing the enemy. Wrapped in an armored battlesuit, Cam finds purpose amidst the horror and destruction of the war, and the opportunity for a new sort of friends and family…if he can break the habits of a life spent alone, trusting no one. And, if he can survive... Rick Partlow returns with another kickass Military Sci-Fi epic. It's perfect for fans of Jay Allan, Jasper T. Scott, and Scott Bartlett.

Home Front
2020
Cam Alvarez was finished with war. But war isn’t finished with him. Hausos is a peaceful farming colony. Once controlled by the Tahni, it's now settled by a collection of homeless refugees and war veterans, among them Cam and Vicky. Their life is pleasantly boring, quiet enough for demons from the war to nag at the corners of Cam’s mind on lonely nights. He fights the demons back with willpower and alcohol, determined to make this place home. But the peace doesn’t last. Serpents show up in their pastoral Eden, smugglers from the Pirate Worlds caching weapons on the farms of their neighbors, taking advantage of the colony’s isolation and lack of law enforcement. Cam is worried but he’s a civilian and it’s none of his business. However, the smugglers are just lackeys for the real mastermind, a former colonel in the Tahni Imperial Army, leading a group of disaffected Tahni soldiers in a quest for revenge against the humans who toppled their society. Will Cam and Vicky be drawn back into the fight against an old enemy? Will fate finally catch up with them, here on their home front? The 5th installment of the bestselling Drop Trooper military sci-fi series is here!

Shock Action
2021
Cam is a Marine, not a spy. That’s what he keeps trying to tell Fleet Intelligence, but when he and Vicky signed back up, they agreed to follow orders. And their orders are to keep working for the Corporate Security Force and find out what the private paramilitary force knows about Zan-Thint and his plans to use Predecessor technology against the Commonwealth. The trouble is, the CSF doesn’t seem to care about Zan-Thint anymore. They send Cam and Vicky and a crew of mercenary Drop Troopers to an isolated mining world called Portent. Their job? To put down a rebellion by wildcat miners who don’t want the Corporate Council stealing the fruits of their labor. Somehow, they’ve been able to hire the baddest mercenaries in the Commonwealth to hold onto their planet. Stuck leading a crew of cutthroat mercenaries who want nothing more than to slaughter the wildcat miners and take their rhenium ore, facing down an even more cutthroat band of mercenaries who’ll kill anyone they consider a threat, Cam and Vicky try to negotiate a course between the two and figure out who’s actually paying the mercenaries and why the Corporate Council is really interested in a backwoods rhenium mine. Because nothing on Portent is as it seems…and their allies might be just as ready to kill them as their enemies. Book 7 in the Amazon Bestselling Drop Trooper series by Rick Partlow is here.

Drop Zone
2022
Cam Alvarez just wants to go home. He just isn’t sure where home is. For Fleet Intelligence Colonel Marcus Hachette and the crew of the Orion, getting home means finding the gate the Predecessors used to travel halfway across the galaxy and using it to return to Earth. For Sgt-Major Ellen Campbell, the woman Cam still thinks of as “Top,” home is the Marines. For Vicky Sandoval, home is wherever the she and Cam can make a life together, whether that’s back in the Commonwealth or right there in this strange new part of the galaxy. But the only way for any of them to find a home is to hunt down the mysterious Seekers, the faction of the ancient alien Predecessors who were tracking the source of the mindless Skrela war drones which had chased them off Earth tens of thousands of years ago. The Seekers have the gate and, just as importantly, they know where to find the demonic Skrela and put an end to them. But as dangerous as the hordes of Skrela drones may be, the weapon the Seekers have created to fight them may be just as deadly…to Cam and the others humans tracing their steps.

Listening time 7 hours 3 minutes
So close to home... And yet farther away than ever. Cam, Vicky, and the others follow the jump gate line into the Reconstructor systems, hoping to find the Northwest Passage back to Earth…back home. Instead, they find death and destruction. And an ancient mystery. Something has wiped out one world after another, not a fleet of aliens, not a natural disaster, but a single enemy. A remnant of an old war, a doomsday weapon in the form of an insidious contagion that could infect one of their own. And if it does, it won’t just be the end of Cam and the crew of the Orion…it’ll mean the end of the human race.
