In the wake of the complete destruction of the luxury yacht Persephone, three people are left alive who know the truth about what happened and two of them are lying. Only Frances Mace, rescued from the ocean after seven days adrift with her friend Libby (who died of thirst just before rescue), knows that the Persephone wasn't sunk by a rogue wave as survivors Senator Wells and his son Greyson are claiming it was attacked. In order to insure her safety from the obviously dangerous and very powerful Wells family, Libby's father helps Frances assume Libby's identity. Frances has spent years in hiding, transforming herself into Libby, and she can no longer allow the people who murdered her entire family and Libby to get away with it even if she had been in love with Greyson Wells. After years of careful plotting, she's ready to set her revenge plans into motion. The game has just begun, and Frances is not only playing dirty, she's playing to win.
