Eternal Contract (Harlequin Comics)

As a teenager, Adrien was infatuated with Chay Haddon, and was devastated when her family banished him, claiming he'd betrayed their trust. Chay vanished vowing revenge....

Adrien is shocked when, years later, the tables are turned and she finds herself at Chay's mercy. Now rich and devastatingly handsome, he's the only one who can save her from scandal. But he has a price: he'll help her, but only if she becomes his mistress!
