Open to Possibilities by Carol Lynne
Gabe Whitlock finally has a home to call his own, but still yearns for the one thing missing in his life-a family. All long legs and lean muscles, Rex Cotton offers a temptation Gabe finds hard to resist. With no rain in sight, Gabe and Rex are forced to come up with an idea to save the ranch and the cattle. When they hire a geology student to help look for oil, they're both surprised at their reaction to the tall, blond Boone Fowler.
Once this threesome of Alpha males comes together, Gabe's whole world changes.
