Zandra Curtis’s world is turned upside down when she finds out her husband has cheated. But she doesn’t believe in throwaway marriages, and she won’t let go without a fight. As Zandra tries to heal her marriage, she is also trying to figure out how to heal the lesions on her French Mastiff’s joints. Dog coach Cason O’Connor, with his easy-going manner and good looks shows up at just the wrong time and Zandra, ever-faithful to her husband, keeps her distance. Cason quickly falls in love with the Curtis’s Mastiffs, but he’s careful about getting close to the attractive—but very married—owner. Having been hurt by a cheating fiancée, the last thing Cason wants is to cause problems for the young couple. Can Zandra find a way to convince her husband to fight for their marriage? Or is she fighting the wrong fight altogether?
