Love in the Time of Scandal by Caroline Linden

Penelope Weston does not like Benedict Lennox, Lord Atherton. He may be the suave and charming heir to an earl, as well as the most handsome man on earth, but she can’t forget how he abandoned a friend in need—nor how he once courted her sister, Abigail. He’s the last man she would ever marry. If only she didn’t feel so attracted to the arrogant scoundrel…

Once upon a time, Benedict thought he and Penelope got along rather well. Though he needs a wealthy bride to escape his cruel father’s control, spirited Penelope just doesn’t suit his plans for a model marriage—until a good deed goes awry, and scandalous rumors link his name to Penelope’s. She might not be the quiet, sensible wife he thought he wanted, but she is beautiful . . . beguiling . . . and far more passionate than he ever imagined. Can a marriage begun in scandal become a love match, too?
