Welcome to Beaumont Cove, a slowly decaying tourist town at the edge of the world, and the place where Maggie James's worst fears for her estranged twin sister, Lilly, have come true. Lilly is dead, and Maggie has arrived to identify her body. Lilly's husband, Mike, is in custody for her murder. With his long history of abuse, no one in town is surprised at the inevitable end to their stormy marriage, least of all Maggie. All she wants is to clean up her sister's affairs, see Mike punished, and get out of Beaumont Cove. With the help of the local sheriff, a retired private investigator, and a strange but friendly carnival psychic, Maggie begins to uncover the truth about what really happened to her sister. But the truth comes at a price, and soon Maggie finds herself walking a dark path toward the same deadly trap that killed Lilly. The more Maggie discovers about her sister's final days, the more she realizes that nothing is as it appears in this strange boardwalk town.
