Knight of Christmas - The Rakes of St. Regent's Park, #3

Returning from Canada after ten years away, Brandon Knight has one goal in mind: Vengeance. But his plan is hindered when he discovers that his foe, the Earl of Oakby, has died. Instead, he focuses retribution on the lovely widow, Lady Angeline, with whom he shares a dark and agonizing past. Angeline is damaged and feels nothing inside. After suffering through devastating loss and a horrible marriage, she and her son are destitute.
Bran steps forward with an outrageous offer, and Angeline has no choice but to accept. Considering that the attraction still sizzles between them, Bran will have to surrender his plans for revenge to bring Angeline back to life. They once loved each other, but doubt they can move beyond their grievous pain. However, it's Christmas, and anything is possible.
