Wilde, Lori. Cupid, Texas novel.

"One minute, Rhett Lockhart is a love 'em and leave 'em bull rider with a slow, sexy smile, a swagger, and not a care in the world. The next, he learns his free-wheeling days are over: a baby has been abandoned in the hospital, and there's no question: he's the father. But from the first moment he gazes into his daughter's eyes, he knows the moment has come to say 'no' to no-strings. It's time to grow up. Standing in his way is the baby's foster mother, Tara Alzate, who doesn't quite believe Rhett is ready to change his ways. Still, she's not not immune to his considerable charms. So when he proposes a marriage of convenience and shared custody, against her better judgement, she says "I do." Can Tara tame this wild cowboy and make her own, long-buried dreams come true?" --Amazon.com
