Cassie Lockwood has traveled with her father's Wild West Show as long as she can remember. An amazingly skillful trick rider, likened by some to the famous Annie Oakley, she stayed with the show even after her father's death -- it was the only home she knew.
But when Cassie discovers that the show's manager has driven the show into debt -- and absconded with what little money was left -- she's devastated beyond reason. With nowhere else to go, Cassie decides to find the hidden valley where her father dreamed of putting down roots. With only one clue to guide her, she sets out with two unlikely friends, leaving behind the show -- and a bundle of heartache -- to begin a wild and daring new adventure.
