Ben Gold, former airship pilot has lost everything: his airship, his friends, and Miranda, the woman he loves. All that he has left is a thirst for revenge, a reckless plan to sate it, and some journal entries from Miranda to help ground him in the chaos. As he spirals out of control, he must survive old friends, new enemies, and of course Ferals, the mindless, violent victims of the global pandemic that shattered the world. Meanwhile, the Cabal, a group of scientists on the floating city of Valhalla, are using the disease as a weapon while the militant Valhallans continue their raiding and destruction across the continent. When raiders from Valhalla massacre a town of innocents, Ben finds a new purpose in doing anything he can to undermine their power. Ben must reunite with old friends and find new ones if he is to succeed. Can he overcome the forces arrayed against him in time to save himself-and maybe the world?
