Despite her illustrious title, Camille, Duchess of Hereford, remains what she has always been - a pariah. Though her title means she's technically accepted by London Society, the rebellious widow with her burgeoning interest in the suffrage movement and her American ways isn't exactly high on every hostess's guest list. But Camille starts to wonder if being an outcast is not without its perks when the tantalizing answer to her secret fear appears in the shape of Jacob Thorne, the illegitimate son of an earl and co-owner of London's infamous Montague Club. Jacob is used to making deals with his club members - he's just not accustomed to them being beautiful women. Nor have the terms ever been so sweetly seductive as Camille's shocking proposition. To finally buy his own club and gain the crucial backing of investors, Camille offers Jacob the respectability of a fake engagement with a duchess. In return, the tempting widow has one condition: she wants Jacob to show her if it's possible for her to experience pleasure in bed. The lure of such a bargain proves too delicious to resist, drawing the enterprising rogue and the wallflower duchess into a scandalous game and an even more dangerous gamble of the heart.
