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.

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.

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.
