Calder country / Janet Dailey.

"1920s, Blue Moon, Montana. The small cattle town is alight with the excitement of cars, telephones, and airplanes. But as new inventions and new roles for women collide with Prohibition and the rising battle between gangsters and the FBI, Blue Moon finds itself--and some of its most infamous residents and powerful families--at a crossroads, and in battles of their own, between hearts and minds... Heir to the Hollister Ranch on his mother's side, Mason Dollarhide is back home after a five-year prison sentence for smuggling bootleg liquor. Cynical and daring, he's already up to his old tricks, having his goods trafficked to him by plane... Until the pilot is injured in a crash and captured by federal agents. Ruby Weaver learned to fly from her smuggler father. To keep him out of prison, she agrees to take over his route and go undercover to help the Feds break up a bootlegging ring. Mason is only one part of that large operation, but he's the rugged, rebellious, and tantalizingly irreverent part that makes an impression. Against her better judgement, Ruby finds herself falling for him, fighting an attraction that could jeopardize them both, while harboring a secret that could destroy any hope of a future together... Mason has never met a woman quite like Ruby. Not only is she brave and beautiful, but she somehow understands his ways--and may even inspire him to change them. The first step will be trusting her enough to open his heart... While the fire between Ruby and Mason smolders, other star-crossed Blue Moon romances blaze, as old family rivalries between the Dollarhides and the Calders continue. But when tables unexpectedly turn, some dreams may go up in smoke..."-- Provided by publisher.
