When her overprotective family tries to curtail her activities, spirited and independent debutante Fiona Garrity decides marriage is her surest way to freedom. All she needs is an accommodating, and preferably not too perceptive, husband with his own hobbies so that he will not interfere with hers. Destiny puts her into the path of a reputedly staid and scholarly earl. He would be the perfect candidate…if only his grey eyes were not quite so magnetic, and his virile nearness didn’t affect her in such a stimulating manner…

After the death of his first wife, Thomas Morgan, the Earl of Hawksmoor, has sworn off love. He is torn between his duty to produce an heir and his true passion: his work as an agent of the Crown. Fate gives him a solution when a dazzling debutante proposes a practical union that would allow them both to maintain private lives. She would be an impeccable choice…if only her heavenly gaze didn’t lay bare his secret needs and her delectable form didn’t tempt him to unleash his darkest desires…

Fiery passion threatens the negotiated rules of Fiona and Hawk’s marriage. As desire turns into love, their secret lives collide. Will their marriage of convenience survive betrayal and danger to become a love for all time?
