Time is running out for the star crossed lovers, the teenagers thrown together by fate who were supposed to be trying to kill each other. The undead infection is spreading in Scarlet, slowly worming its way through her body.

The cult begins its advance on the free states headquarters and Casey's ruthless cannibals are gathering their forces for their own attack. No one gets to sit this one out. Everyone fights.
