With their Safe Zone overrun by the undead, taking refuge in the mountains seems like the safest bet for Rose, Tom, and the other survivors. There’s one catch, however—between last spring’s human exodus and a neighboring group’s stockpiles, there’s no food left to scavenge. They know to be wary of people and zombies, but a new adversary proves itself just as relentless—hunger. Supplies are slim in the wilderness, and living off the land is easier said than done. As winter sets in, and their food dwindles to nothing, they discover how far they’ll go to save the ones they love.
