Six years ago, the world was plunged into darkness. Five years ago, it got a second chance. Now, the fight for what's left begins....

They called it the Purge.

History books call it the Purge, and it altered the course of human history. A breed of seemingly unkillable creatures that once lurked in the shadows of mankind's past finally revealed themselves. Driven by an insatiable lust for human blood, these monsters - dubbed "ghouls" by some - consumed the globe in one bloody, awful night.

Their numbers growing exponentially through infection, they felled the unprepared governments of the world with hardly any resistance. In the yearlong nightmare that followed, survivors were turned into chattel for the generations of ghouls to come. Most chose to cooperate, but a brave few fought back, and thanks to their sacrifice, the ghouls were defeated and driven back into the darkness.

Humanity was given a second chance, but the world post-Purge will never be the same. The cities have been abandoned, technology is limited, law and order is nonexistent, and survivors live off the land in small, isolated communities in the countryside. Nightfall is no longer the harbinger of doom it once was, but the night will never be completely terror-free. Though vastly smaller in number and weaker than they've ever been, the ghoul menace lingers.

But the monsters are now the hunted. Men and women who suffered unimaginable horrors under the yearlong Purge roam the land, seeking out the creatures wherever they hide. They call themselves slayers. They are skilled, dangerous, and they have scores to settle.

Two strangers on a dangerous road.

Wash is a young slayer scouring what's left of America in search of one very specific ghoul. He will find it even if he has to brave hell itself to do so. Ana is a woman who is not what she seems - cunning, smart, and far more capable than she lets on.
