The shotgun wedding
(Book)

Series numeration from Goodreads.com.

"Bo Creel and Scratch Morton are mighty proud. They managed to deliver five mail-order brides to the New Mexico mining town of Silverhill in one piece. The town is so grateful, they want to make Bo their marshal and Scratch his deputy. Bo and Scratch are happy to accept the job--and even happier to attend the weddings of the fine young women they brought here. Cecelia has two young suitors--a well-off rancher and a low-born miner--but one of them is not what he seems. Tomboyish Rose has gotten herself roped into a cow-rustling scheme--with the wild young buck who's stolen her heart. Luella has a not-so-secret admirer of her own, a former journalist who's making headlines--with a gang of Mexican bandits. And the refined Jean Parker thinks she's finally found a suitable match in this raucous boomtown. But it turns out her educated doctor has a dishonorary degree--in killing. With marriage prospects like these, Bo and Scratch will have to fight tooth and nail to keep the ladies safe and sound--and a real shotgun wedding is about to begin." --
