In the third book of the Keystone Stables series, perfect for girls who love horses and horse fiction, Skye faces a new challenge when a runaway girl becomes the newest foster child at the ranch—and soon becomes Skye's nemesis as well. Tanya Bell seems intent on making Skye's life miserable. Even though Skye's foster parents agreed to take Tanya in after she got caught shoplifting and ran away from home, the new girl seems more focused on causing fights and wreaking havoc in the barns than facing the reality of her situation. When one of the stable's new mares arrives with a complicated pregnancy, Skye thinks she may have found a way to keep Tanya focused on something other than herself. But as the mare's and foal's lives become endangered, both Tanya and Skye face the test of their lives as they need to work together to overcome the challenges and surprises ahead.
