Betrayed by his fiancée and his best friend, Chase Garrett heads out on the road with the American Extreme Bull Riders Association, determined to ride hard and keep a wall around his heart. But during a competition, three-year-old Riley Barrett bursts through that barrier when he throws himself into Chase’s arms, insisting Chase is his daddy. And Chase's walls collapse further when he meets Riley's mother–beautiful, vulnerable, sexy Maddy.

A widow for only a year, Maddy Barrett is stunned by her son Riley’s outlandish assertion that Chase is his father. She tries desperately to convince Riley that his father has not come home to them. When Chase and Maddy join forces to help her son, she finds herself falling fast for the sexy, hard-working bull rider—wishing he truly could be the man for Riley, and the man for her.
