What if a predator becomes the prey? What if a hunter has eyes on your child?

In a twisted game of cat and mouse, Detective Madison Chase must outwit a serial killer targeting sex offenders—before her own daughter becomes the next victim.

October in Fort Worth takes on a sinister hue for Penny Grimes. She's not just a vigilante; she's a poetic executioner, leaving headless pedophiles as her gruesome calling cards. Each murder scene is adorned with a chilling rhyme, taunting the police and, in particular, haunting veteran homicide detective Madison Chase.

But Penny has a darker agenda. She's set her sights on Chase's daughter, Emily—a blonde, blue-eyed four-year-old who is the living image of the child Penny has always yearned for. Unbeknownst to Chase, while she's hot on the trail of Fort Worth's most elusive serial killer, Penny is plotting to kidnap Emily.

To divert Chase, Penny masterfully frames her for one of the murders. Now, Chase isn't just fighting to solve the case; she's fighting to clear her name and protect her daughter from the clutches of a deranged predator.

In a pulse-pounding race against time, Madison Chase must navigate a maze of deceit, vengeance, and dark motives. Can she apprehend Fort Worth's deadliest killer before her family is torn apart forever? The stakes have never been higher.
