The Dolan Girls — S.R. Mallery

Set in Nebraska during the 1800s, whorehouse madams, ladies of the night, a schoolmarm, a Pinkerton detective, a Shakespeare-quoting old coot, brutal outlaws, and a horse-wrangler fill out the cast of characters. Adult themes are added to the mix, along with colorful descriptions of an 1856 land rush, Buffalo Bill and his Wild West Show, Annie Oakley, bank/train robberies, small town local politics, and of course, romance. Two, in fact!
