Once a Mistress — Debra Mullins

Hard-Hearted Captor...
He was the dark, dashing rogue of Diana Covington's fantasies...until he literally swept her off her feet, swooping across the ship's deck on a rope to rescue her from her evil abductor. But now Diana is the captive of this handsome, charming pirate--and who will save the beautiful heiress from the bold stranger whose burning kisses inspire such unmaidenly thoughts?

Or Man of Her Dreams?
Alex Rawnsley is merely living up to his rakish reputation when he claims lovely Diana as his mistress--but he has no intention of plundering her fiery innocence. This Earl-in-disguise hides behind tales of pillage and seduction in order to win vengeance--not love. Yet the mere thought of one passionate night with the defiant beauty is more than enough to tempt Alex to forget his pledge to return her home--untouched.
