Miles Beresford has a wicked reputation, but will do anything for his twin brother Justin, the Duke of Wiltshire. Even if that means assuming his identity for a week to suss out the intentions of some young marriageable chits fresh from the London season. But when Rebecca Livingstone stumbles out of a coach and into his arms, he realizes that he might be in serious trouble – and that playing an imaginary duke to win her over may be slightly over his head. Does Rebecca love him or the dukedom, and can he bear to lose her if he admits he’s just the Duke’s Twin?
