The moment Lucas "Lucky" Welch sees the black-haired, green-eyed boy at the rodeo, he knows. The child is his late brother's son. But why was little Robby kept a secret? He demands answers from the woman claiming to be Robby's mother, Natalie Crosby. But the pretty, protective woman isn't forthcoming. And once Lucky learns the truth behind Robby's birth, he understands. Especially when some family matters get more than complicated. As a bull rider, Lucky knows he just has to hang on tight and keep showing Natalie that his wish is true-blue: to be a daddy--and husband--for keeps.
