Nothing but a little waif of a dog from the Crow Reservation in a dog eat dog world, Cassie wants to make a difference. She can't play soccer, she can't role over and play dead, she can't even speak. What can she do? She's caught salmon in Alaska's streams, she's gone to highschool for four years, she's travelled the United States, she's been a sidekick in her master's flying projects. She has watched all the dog movies and seen all they can do, but she is hoping for her own adventure...to be daring, dauntless, bold...to be a hero in her own right.
