Opportunity doesn't knock twice, but death can...

After making it through the long Alaskan winter, Nick and Jimmy begin building their hard-earned new lives.
But the spring thaw has revived more than trees and green grass. For the two brothers, killing crazies has once again become an everyday reality.

Then their lives change forever when Nick receives Lusa's call for help and a new threat is revealed. Launched into a world worse than the one they escaped from a year ago, Nick and Jimmy must face a new enemy, one which promises to wipe out the rest of humanity...one bite at a time.
