Fourteen-year-old Corgan is a genetically engineered soldier, raised in an isolated computer-generated environment for the purpose of one war, now only two weeks away. Suddenly, his sheltered existence is shattered when he meets his fellow warriors: ten-year-old genius Brig, a mutant military strategist, and Sharla, whose computer decoding abilities are unsurpassed.

In this fast-paced adventure, the Landons trail a wounded wolf in Yellowstone National Park. The park is abuzz with rumors of a wolf attack. Meanwhile, a killer stalks the woods.

The book's afterword, by Yellowstone's Michael K. Phillips, explores the park's Wolf Restoration Program.
