Novelist JB Blackwood is on a cruise with her husband, Patrick, to celebrate their wedding anniversary. Her one-time professor, Patrick is much older than JB. A maverick when they met, he seemed somehow ageless, as all new gods appear in the eyes of those who worship them. He is a film director. A cult figure. But now his success is starting to wane and JB is on the cusp of winning a major literary prize. Her art, that has been forever overseen by Patrick, is starting to overshadow his.

For days they sail in the sun. They lie about drinking, reading, sleeping, having sex. There is nothing but dark water all around them.

Then a storm hits. When Patrick falls overboard, JB is left alone, as the search for Patrick's body, the circumstances of his death and the truth about their marriage begins.
