Full Moon Rising (Harlequin Intrigue #316)
Laura Gordon

As lawyer to pearl baron Henry Marston, Adam Dean was sent to "retrieve" Henry's adopted daughter, Tory - twenty years after she'd been sent away. Each night, he fought the urge to look into her eyes and tell her his terrible secret.
Together, Tori and Adam rose above the tension that sizzled between them and began to uncover her past. The truth would finally free Tori, but would it bind Adam to the past he longed to escape.
