When a young woman is found murdered in the woods behind the local veterinarian's office, the four Hurley sisters (Daisy, Lily, Rosie, and Amy) assume it is a tragedy that has nothing to do with them. But when the woman is identified as Skylar Smith, the sisters make an ominous connection: Skylar had threatened the eldest sister, Daisy, with a terrible secret just eight weeks before she was found dead.
Each of the sisters is soon targeted by an unknown attacker who seems hell-bent on destroying the Hurley family altogether. But who can they trust when the truth is shrouded in darkness?
