A Hunter who has seen the end of the world. A Champion swayed by a promise of power. A Guardian who has lost faith in humanity.
Seth Wright knows he's going to die in the Demon War. The squad captain has one year to improve his odds of surviving his mandatory four-year tour. The only tools at his disposal are the Academy's military games, obsolete training manuals, and an ancient training program that used to train Demon Hunters for combat. And then he meets a sole survivor of demon raid who's hell bent on ruining his plans.
Seth's torn between trusting the young survivor or activate the ancient training program that might exterminate the remnants of humanity before the demons get a chance to invade.
