The Reef - Nora Roberts

Marine archeologist Tate Beaumont has a passion for treasure-hunting. Over the years, she and her father have uncovered many fabulous riches, but one treasure has always eluded them: Angelique’s Curse—a jeweled amulet heavy with history, dark with legend, and tainted with blood. In order to find this precious artifact, the Beaumonts reluctantly form a partnership with salvagers Buck and Matthew Lassiter.
