In this chaotic world of uncertainty, Hoss wakes up with his memory gone. His only companion, his wolf named Wolf.
Hoss takes refuge in a castle that used to be an old folks’ home. In that castle, he finds himself with other survivors who each had their own story of survival to tell. With their lives at stake, Hoss takes charge of the group and tries to survive in a dangerous world fraught with constant danger and evil.
Fighting other people for survival is one thing. But fighting against giant rats, venomous brightly colored snakes, dinosaur-like alligators, monster sharks, cannibals, and people who were drugged to be vicious killing machines is another.
How long can they hold out? How long can they stay alive?
Welcome to the day the world ended.
