In the Colorado frontier, whelping is never an easy time for werewolves, so when Bryce Crichton's alpha female, Lucille whelps, most of the pack tends to scatter except for the few needed to maintain the ranch. It's always at those inopportune times that problems arise. His prize stallion goes missing, so Bryce and ranch hand and pack member Tim take off on its trail only to find trouble with vampires that threatens to destroy their entire pack. Can Bryce defeat the vampires trying to take over his territory in time to hear his pups first howls?
