Mountains, snowboarding, parties, skibunnies-it should be a winter paradise for sixteen-year old Charlie and his younger brother Jack. But the temperature plummets on their fun when the undead climb the slopes. A zombie, an avalanche, and the law chase Charlie, while the outgoing Jack leads new friends Maddie and Christian down the slopes and through town as it swarms with the ravenous undead. When the brothers join forces against the zombies to rescue their parents, they learn how much stronger they are together.
