A Prisoner of His Past

Gabriel Ridgley, the Marquess of Tremont, is dubbed The Angel for his pristine reputation. Yet he harbors a dark secret: a spy during the Napoleonic Wars, he bears deep and dangerous scars. When he meets Miss Dorothea Kent, a delicate virgin, he is torn between carnal desire—and the need to protect her from his inner demons.


A Captive of Her Passions

Despite a frail constitution, Thea Kent has strength of heart and spirit. A wild attraction blooms between her and Gabriel, a widowed aristocrat with tortured eyes, but he resists the pull between them. When fate places his disabled son in her care, she’s determined to safeguard the boy—and unravel the mystery of Gabriel’s past. 


Freed by Love and Passion
