Three young heirs, imprisoned by an unscrupulous uncle, escaped—to the sea, to the streets, to faraway battle—awaiting the day when they would return to reclaim their birthright.

Sebastian Easton always vowed he would avenge his stolen youth and title. Now back in London, the rightful Duke of Keswick—returning from battle a wounded, hardened, changed man—cannot forget the brave girl who once rescued him and his brothers from certain death.

Lady Mary Wynne-Jones paid dearly for helping the imprisoned young Lords of Pembrook, and she remembers well the promise she made to Sebastian all those years ago: to meet him once more in the abbey ruins where they shared a bold, forbidden kiss. While Mary is now betrothed to another, a friendship forged with dark secrets cannot be ignored. Unexpected passion soon burns dangerously between them, tempting Sebastian to abandon his quest for retribution and fight for a love that could once again set him free.
