If Molly Hatfield's purple attire doesn't blind you, her dazzling smile will.  She doesn't just sing to the cattle, she puts on a whole show. If only she wasn't so stubborn about her brother's care.  Or so distrustful of a certain handsome doctor...There is nothing Molly wouldn't do for her teenaged brother, Donny. Blaming herself for the accident that left him wheel-chair bound, Molly has dedicated her life to his care. But in 1896, gainful employment for a woman is hard to come by. So when Molly learns that an eccentric rancher in Cactus Patch, Arizona, is looking for an heiress--someone to take over management of the ranch in exchange for future ownership--she jumps at the chance to provide a real home for her brother. If she proves to have a knack for ranching and agrees to remain single for life, the ranch can be hers.
