Cowboy Werewolf Massacre

The year is 1871. A mysterious force stalks the Wild West, killing settlers and even the toughest outlaws. Soldier-turned-bandit Jack Stark is given a choice: Hunt down whatever's out there, or face the noose. The chase will take him from dangerous mining towns and snowy wastelands to ancient caves that hold the most terrible secrets... and eventually into the middle of one of the biggest disasters in U.S. history. As Stark soon learns, it's not just his life at stake: the country's future rests on his ability to shoot fast and think faster.
