Luke by Jan Irving

Wandering cowboy Luke Walker is at the end of his rope after his girlfriend abandons their newborn daughter. A terrified new father, he's grateful to meet Dr. Morgan Gallagher. Morgan recognizes that he and Luke could help each other: Luke can rebuild Morgan's property and land so Morgan can have the horses he wants, and Morgan can provide the younger man with a safe place to raise his daughter. In theory, it should work out perfectly, except that Morgan is instantly attracted to Luke-a straight man-and sharing the same cabin and caring for the baby is a more intimate arrangement than he'd imagined. A Spin-off of Sylvan
