Josh King is perfect, or at least he tries to be. Loyal, hardworking, and honest, he can't stand to be lied to or laughed at. Nicknamed "Saint Josh" by his three older brothers, his hidden soft side is reserved for his beloved cattle dogs and his best friend, a wiry little cowboy named Sam. But when Sam betrays him, Josh decides never to trust again. He wears his anger like a shield, keeping the world at bay until his meddling sisters-in-law decide to intervene. They're convinced Josh needs to heal and change, and they think they have the perfect plan.

Josh is predictably angry about the girl they bring to the ranch for him. After all, he already has a girlfriend. But his brothers won't listen to reason; instead they listen to their wives. Now Josh must try to dodge the woman living in his house by any means necessary. And as for the girl, she might be the key to unlocking Josh's stubborn heart, if only he'll give her a chance to try.
