FAMILY MATTERS Mackenzie Vaughn is determined to learn to run the Montana ranch she's inherited—even if it means relying on Chet Granger. Years ago, the serious (and seriously handsome) cowboy broke up her relationship with his younger brother, and Mack doesn't want to remember that heartache. Chet knows gorgeous, spunky Mack is off-limits. His brother would never forgive him, and Chet always puts family first...until he can no longer ignore his feelings. If Chet gives in to his heart, he'll lose his brother and the ranch they share—if he doesn't, he could lose Mackenzie forever.
