Randall Aviks

A small community is besieged by vampires. After he watches friends ravaged in a convenience store, a lone avenger goes off to do battle with the undead, armed with shotgun, chainsaw, and Holy water. Later he finds other survivors and they try to stay alive long enough to do battle with Liven, king of the vampires.

Three people -- a man with the power to heal, his interpreter (since he can’t speak) and a soldier to protect them, time-travel from the future to rescue a tech genius who is pivotal in saving the Native American race.

Turns out, Native American ancestry causes immunity to the zombie virus sweeping the nation.
