Mateo Lopez, honorably discharged from the Marine Corps on medical leave, is struggling to rebuild his life. The spinal cord injury that left him feeling like a broken man resulted in his inability to ride the horses he loves and works with on Round Top Ranch. The new horse trainer at the ranch, however, has decided that this isn't acceptable. Claire Windsor, a spirited, London-born spitfire of a woman, has come to begin a new program to turn the horses into therapy animals. She turns Mateo's world upside-down, and try as he might to avoid her, she keeps inserting herself into his life. As their plans for the ranch clash, so too do their hearts...making all things fair in love and war.
