Desert Adventure! When Christie Kimball and her family start a new life on a run-down Arizona ranch—once a bustling stagecoach stop in the Old West—their lives take an unexpected turn. Christie and her brother Neal have a secret plan to transform the old ranch into a money-making tourist attraction for the motel their father wants to build. But when the Kimball kids and their Navajo friends go exploring in the desert and stumble on a mysterious treasure chest hidden deep in a cave—the real adventure begins... Soon a Ghost Town, a long-lost letter, and a concealed valley carry Christie and Neal into a lot more excitement than they ever dreamed possible.
