It is the end of the world.

They call him Eagle, like the grand and beautiful bird that symbolizes freedom. During these dark times, when humanity is experiencing nothing but suffering, a man with such a powerful name should be a beacon of hope, yet he is anything but.

Her name is Autumn, but she hasn't said this name or much of anything else in the four years since the fall of civilization. A shell of her former self, living wild in a cave at the bottom of a ravine, Autumn is accustomed to being alone. She prefers it, actually, especially when her only options for company either try to kill her, or worse, to lock her up inside their walls.

Captured by Eagle's people, Autumn is suddenly thrust back into the land of the living, but she would hardly call it living. The community of Purgatory is full of sinners, the most evil of whom seem to have set their sights on her.

In an act born of anger and defiance, Eagle becomes Autumn's unexpected savior, forcing these two solitary people into each other's broken worlds. Neither knows quite what to make of the other, but one thing is certain. To survive Purgatory, they must learn how to rely on each other, a feat that could possibly teach them both how to live again.
