Shedding the wreck of a bad marriage, Tommi Winters strikes out on her own. Her problem has never been trusting men, but finding one who is trustworthy. A marine biologist at La Jolla’s Scripps Institute of Oceanography, she impulsively takes a scuba diving class on a colleague’s dare in reaction to the numbness that engulfs her at her husband’s sudden exit.
With her underwater class, she discovers a world of pleasure and adventure with its own strict rules for survival – why couldn’t it be this easy in life? She finds the sea a familiar companion and an easy place to shed all of her concerns.
Over a candlelit gathering, an intricate plan to retrieve sunken treasure is hatched by Jason, their scuba instructor and Rick, the divemaster. As they weave their tale of South Sea adventure, Tommi’s class is seduced by the lure of an underwater fortune. Enticed by the younger man who leads their dive trip to Fiji, Tommi discovers that misplacing her trust this time could end her life when greed surfaces along with the gold. Death and destruction swirl around her as she struggles for equilibrium and then survival, gaining hard-won wisdom and confidence in herself and her decisions.
