In the computer game world of Bow Hunter (Casey's world) there are no deaths, just kills. In the wolf world (Nashoba's world) there have been no kills. For this is March, the Starving Time in the Iron Mountain region of Colorado, when wolves and ravens alike are desperate for food. With the help of a raven, the miraculous Merla, Nashoba must lead his pack of eight to a next meal. The wolf hates being dependent on a mere bird, but Merla is a bird wise beyond her years. And when thirteen-year-old Casey crosses their path, two very different approaches to hunting collide.
