Flexible Standards by Irene Bahrd

After her husband left her for his secretary, Isla needs a change of scenery. With her best friend inviting her to move to Las Vegas, and securing her a job as a librarian, there’s no time like the present to start fresh, beginning with her friend’s bachelorette party.
While at the party, Isla retreats to a small casino bar, avoiding the festivities. Only, her night of solitude comes to an end when she meets Sam—an incredibly attractive and smooth-talking Brit who enjoys an evening of reading, more than a night on the town.

Though they are otherwise an unlikely pair, Sam helps Isla regain the confidence she lost in her past relationship… one org*sm at a time.
