The Marquess of Bromton has just learned that he's a bastard. Feeling his honor is at stake, he attempts to bestow his estate upon a rightful heir by manipulating a high-stakes card game. But the winner demands more than Bromton bargained for—a marriage . . . to his spinster sister. Lady Katherine may be the least marriageable lady in all of England, but a child of their union would be a rightful heir . . .

Scandal has hardened Lady Katherine and narrowed her world to duty and family. There's nothing to be trusted in the Society she left behind . . . especially not the imperious marquess with his single-minded pursuit. Or his knee-weakening kisses. Except, the more their connection deepens, the more Bromton surprises Katherine. But the truth about their courtship could destroy everything . . .
