When a wild pinto mustang, Rebel, and an equally wild new foster girl, Wanda, arrive at Keystone Stables, Skye feels God urging her to reach out and help them, whether they want her to or not. In the seventh book of the Keystone Stables series, perfect for girls who love horses and horse fiction, foster child Skye gets more than she bargained for when the two newest arrivals to the ranch are a half-wild Mustang and a former gang member who may be just as uncontrollable.
