At the height of the French Revolution, a viscount's daughter enlists the help of a man who turns out to be a perilous threat to her family... Sarah Leaford is desperate to rescue her father from the dungeons of Paris, and it seems that her success depends on one man: Gentleman Jack, the greatest thief in all of London. What she doesn't know is that Jack is already well acquainted with her father. Years ago, Lord Carleigh framed Jack for murder, leaving him a ruined man destined for the gallows. Now Jack has a chance for revenge—but to take it, he must resist falling for the beautiful noblewoman and her mysterious, untamed magic. Drawn together by a dangerous mission, they must not surrender to the passion that flares between them. Sarah and Jack are not simply a maiden and a thief, and more lives than theirs are in peril. So much is at risk that even the dead take notice.

He inspires Helen's utmost distrust until he gives her a stunning sapphire necklace—a gift that traps her under his dark spell. Redfern's mission is to stop the murderous Hellfire League, but he will risk that and more to save—and win back—the woman he adores.
