Giving away her baby for adoption was the second biggest mistake of Sierra Powell's life. But after a miraculous turn of events, she is reunited with her toddler son and they return to Arizona. Too bad Sierra's first mistake is waiting for her there—Clay Duvall, a much too charming cowboy. And onetime love of her life.

Clay is not about to let go of the opportunity to raise his flesh and blood. He proposes co-parenting—meaning Sierra and Jamie have to move close to him. Real close, as in onto his property. As far as Sierra's concerned, he has no say in her son's life; Clay was the one who walked out on their relationship.

Will the sparks between Clay and Sierra set off the formerly feuding Powell and Duvall clans…or will they rekindle an old passion?
