The mysterious sinking of a research ship off the coast of New England sets the scene for Neggers's (Kiss the Moon) romantic suspense. Marine biologist Riley St. Joe and her childhood nemesis, John Straker, form a shaky alliance when Riley's grandfather, a famed maritime explorer, becomes the prime suspect in the murder of the ship's captain. John, an FBI agent on leave due to post-traumatic stress syndrome, comes out of seclusion to assist Riley in her quest to clear her grandfather--which gives the pair plenty of opportunity for romantic sparring and reminiscing.
