Worst Duke Ever by Eliana Piers

Bad never looked so good

Lady Seraphina is facing scandal and ruination if the secret of her father’s debt gets exposed. She’s run out of options. Except him. Him being the evil one. The debt holder. One night pleading for his mercy may very well change her mind—and her heart—toward him though. All it takes is one kiss.
Sebastian, Duke of Ravenshire, has always paid his own debts, ever since he learned his lesson as a boy. So when Seraphina sneaks into his house one night with a proposition to eliminate her father’s debt, he’s not the least bit interested. That is, until she sweetens the deal with an offer for a marriage of convenience.
Sometimes all a little bit of evil needs is a whole lot of good love.

If you like lightning fast reads of women saving themselves from the brink of scandal, then you’ll adore Eliana Piers’ duology regency romance stories about the Everly Sisters.
