Life — and death — spins savagely out of control. Familiar faces scramble to survive the brutality, and wrenching betrayal lurks around every corner.

No good deed goes unpunished in a zombie apocalypse: The tables turn for Rose, Sun, Spears and Anna. The winter brings snow — and fresh horrors.

Inside, Rose and Anna are warm, but are they safe? A loose coalition coalesces, but the tension grows, everyone is armed, and an ax has gone missing.

An outgunned Rose must make a life-and-death decision. The war comes home when dangerous groups converge on a haven, catching Sun in the crossfire.

Hungry, hurt and alone, Spears encounters a talkative stranger who claims to know him. A mysterious rider on a pale horse passes in the wilderness.

Treasure brings out the worst in everyone, but trust is the most precious commodity in this wasteland. Rose grasps at straws, and Sun risks it all.

Time for takeoff. Out at the airstrip, old allies reconnect, new cohorts seize the opportunity, and escape seems tantalizingly within reach.
