Today is the biggest day of Cole Ristler’s life. He’s about to join his wife and unborn child in retirement, an event he didn’t think would ever happen. It’s a cause for celebration, and all that’s left is the ride home. Unfortunately for Cole, the world has other plans. When an unknown phenomenon strikes the planet, man becomes its own worst enemy, transforming into rabid crazies that strike out at the nearest victim, seemingly driven by a single urge: Kill

It's been six years since a terrifying breed of seemingly unkillable creatures emerged from the darkness to topple the unprepared governments of the world, in the process knocking mankind down the food chain. Survivors called it The Purge. A few brave souls rose from the ashes of the old world to fight back, often against overwhelming odds. Led by indomitable heroes, they risked everything to achieve a final, stunning victory over the supernatural "ghouls" in The Battle of Houston. Five years later, what remains of the ghouls have fled back into the shadows.

A girl traumatized by the murder of her tribe. A battle-worn woman who became the perfect machine for survival and the deadliest special operator on Earth. Now, with the entire world collapsing around her and safety–and Alpha Team–10,000 miles away…

Creatures that once lived in the shadows, hidden from humankind, have risen, spreading like a plague across the globe over the course of a single night. Their numbers growing exponentially through infection, these seemingly unkillable creatures have swallowed up whole cities and collapsed unprepared governments. Survivors call it The Purge.
