Out of the Darkness (Heartland #7)

Amy is enlisted to help Prince, a former champion racehorse, recover from devastating burns caused by a stable fire. While Prince's physical wounds are obvious, his emotional state is more scarred and even harder to treat. When Amy learns that Prince's groom was also injured in the fire, she believes he might be the key to the horse's recovery. In the hills of Virginia, Amy works to develop an emotional connection to Gallant Prince, a racehorse that has been severely traumatized in a stable fire, while also trying to deal with her changing relationship with Ty.
