AI Reborn Series by Isaac Hooke

Dead before thirty. Reborn as an AI at two hundred. Eric lives a normal life. He has a job. A girlfriend. He owns an apartment. He matters. And then he dies. He wakes up a couple of centuries later inside an advanced infantry robot whose AI core harbors his consciousness. In industry parlance, he is what's known as a Mind Refurb. Eric is soon thrust into an experimental army unit known as the Bolt Eaters, composed of fellow Mind Refurbs... moreDead before thirty. Reborn as an AI at two hundred. Eric lives a normal life. He has a job. A girlfriend. He owns an apartment. He matters. And then he dies. He wakes up a couple of centuries later inside an advanced infantry robot whose AI core harbors his consciousness. In industry parlance, he is what's known as a Mind Refurb. Eric is soon thrust into an experimental army unit known as the Bolt Eaters, composed of fellow Mind Refurbs. Thrown into the latest cesspools of war and conflict across the world, the Bolt Eaters make short work of any opponents. It's almost a cakewalk for the high-tech robots. His latest deployment is just about to end, and Eric is looking forward to spending the next few months exploring the different virtual reality worlds available to AIs like himself, when aliens decide to invade, stranding his unit in the middle of nowhere, cut off from all support. That's right, the feces has smashed right through the fan, and now he must face the ultimate test with the machines he has come to know as brothers: a deadly game of cat and mouse, played against a technologically superior, utterly alien foe; a game whose stakes include not just their lives, but the lives of every man, woman, and child on the planet. It's time to matter once more. less

Alien bioweapons. Robots with human minds. One man's fight to retain his humanity. Eric never thought he'd live long enough to witness an alien invasion. He was right. He died 200 years ago. But then the army decided to revive him, implanting his consciousness into the AI core of an advanced military killing machine. Right on the cusp of a visit from extraterrestrial invaders... moreAlien bioweapons. Robots with human minds. One man's fight to retain his humanity. Eric never thought he'd live long enough to witness an alien invasion. He was right. He died 200 years ago. But then the army decided to revive him, implanting his consciousness into the AI core of an advanced military killing machine. Right on the cusp of a visit from extraterrestrial invaders. He and his platoon, the Bolt Eaters, now struggle to escape the clutches of the alien bioweapons that have a stranglehold on the planet. The team members grapple, too, with perhaps a bigger problem: their newly awakened emotions. It's hard to be an effective killing machine when suddenly you've developed a conscience. Throw in a wildcard in the form of a rogue Russian AI that wants to slaughter them all, and the Bolt Eaters certainly have their work cut out for them. As the tensions between team members rise, and the odds worsen, the Bolt Eaters do the only thing they can do, the thing they were programmed to do. They fight. Eventually the platoon makes a discovery that could change the course of the invasion. Assuming, of course, that they can overcome their inner demons and survive long enough to use it. less

To live as a man, he must die as a machine. Eric and the Bolt Eaters only just finished saving the world when the aliens decided to return. Now the otherworldly mothership lingers in orbit, watching, waiting. The people of Earth aren’t going to let those bastards strike first this time: the military has hatched a plan to destroy the alien vessel. It probably won't work. In fact, it’s a suicide mission... moreTo live as a man, he must die as a machine. Eric and the Bolt Eaters only just finished saving the world when the aliens decided to return. Now the otherworldly mothership lingers in orbit, watching, waiting. The people of Earth aren’t going to let those bastards strike first this time: the military has hatched a plan to destroy the alien vessel. It probably won't work. In fact, it’s a suicide mission. Which is exactly why they’re sending in the Bolt Eaters: human minds implanted into the most powerful war machines ever created. If the platoon fails, they can simply be restored from backups and sent again. And again. As an added incentive to their success, the military has dangled the carrot of freedom: if the Bolt Eaters triumph, their psyches will be installed into civilian robots and given ownership of their mind backups. It’s a carrot Eric doesn’t need: someone’s gotta save humanity. It might as well be him. less
