Regency Redemption (The Radwells #1-2)

THE INCONVENIENT DUCHESS
Compromised and wedded on the same day, Lady Miranda was fast finding married life not to her taste. A decaying manor and a secretive husband were hardly the stuff of girlish dreams. Yet every time she looked at the dark, brooding Marcus Radwell, Duke of Haughleigh, she felt inexplicably compelled - and determined - to make their marriage real!

AN UNLADYLIKE OFFER
Miss Esme Canville's brutal father is resolved to marry her off - but she won't meekly submit to his decree. Instead, she'll offer herself to notorious rake Captain St. John Radwell and enjoy all the freedom of being a mistress!

Except, St John is intent on mending his rakish ways. He won't seduce an innocent virgin. But Esme is determined, beautiful and very, very tempting.
