About this book

FBI Special Agent Autumn Trent's personal life is stabilizing. Her relationship with SSA Aiden Parrish is secure, and she has filed a lawsuit against her former boss for sexual harassment and assault. Her remaining focus is finding her sister, whom she was separated from during elementary school and has searched for throughout her life. When Autumn's sister surfaces in Florida, Autumn's hopes soar—until she discovers the woman is the primary suspect in a series of murders. Autumn travels south to investigate, only to find her sister has disappeared. Autumn soon realizes her sister is not a fugitive but bait in an elaborate trap designed to ensnare Autumn herself. With her sister in danger, Autumn must place her trust in a man who has the power to destroy both her and her entire team. The case becomes a high-stakes thriller with a shocking conclusion.
