Summer, 1816. A notorious rebel is about to meet her match. . . Lady Georgiana Pendlebury is no stranger to breaking the rules of polite society. But when a so-called 'friend' invites her to a clandestine party, Georgiana is shocked to discover the event is more scandalous than even she could have imagined. So when a mysterious stranger offers help, she accepts, not realising their encounter will turn her life upside down. Later that summer, Georgiana is invited to attend a house party at an infamous castle in Yorkshire. The gathering is a loosely veiled effort to arrange a marriage for the Duke of Northriding, who desperately needs an heir. Duke Gabriel Mauleverer has a terrible reputation as a rake, and Georgiana is happy to be a guest purely for the entertainment, but upon arrival, she is shocked to discover that the Duke is none other than the stranger who rescued her weeks earlier. As the other ladies vie for the Duke's attention, Georgiana is desperate to avoid their shocking secret getting out. But she finds herself caught, unable to avoid Gabriel's gaze. Are they a threat to each other? Or could they be the answer to each other's greatest desires?
