One hundred and twenty years after The Fall, and a hundred years after the grays swept in to pick over the last dregs of humanity, John has found himself bonded to Martok Barden nee Black Hand, one of the "good" grays. Sure, Martok is broke, homeless, and borderline manic, but he's always treated John like an actual person, and sometimes like a friend.

But when Martok puts John's bond up as collateral against a house in the woods that he hopes to turn into a wilderness retreat for wealthy grays, John learns that there are limits to Martok's friendship. Soon he finds himself caught between an underworld boss, a girl raised by feral humans who has nothing but contempt for John, and Martok himself, whose delusions of grandeur seem to be finally catching up with him.

Oh, and something in the woods has been killing people.

John has sixty days to buy back his life before Martok's loan comes due, all while avoiding getting butchered by feral humans, killed by the thing in the woods or having his head crushed by an angry gray. Easy peasy, right?
