Refurbished — 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. 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.
