Harlow Carrenwell is the deadliest weapon in the magical city of Lunameade. As the youngest daughter of a powerful founding family, she uses her lethal, poison-laced kiss to eliminate her parents' rivals. However, Harlow harbors a dangerous secret: by night, she acts as a vigilante, hunting down men who abuse women. Her carefully constructed double life begins to unravel when she targets a man who—impossibly—survives her kiss. That man is Henry Havenwood, her new betrothed. Instead of exposing her, Henry whisks her away to his remote mountain fortress, trapping her in a world of forced proximity and lurking vampire threats. Now, Harlow is caught in a high-stakes game of cat and mouse with a husband she cannot kill, miles away from the safety of her home. Combining the dark, vengeful spirit of *Promising Young Woman* with the tension of an arranged marriage, *The Poison Daughter* is a gripping romantasy. As Harlow navigates the treacherous politics of the Havenwood estate, she must confront an unsettling challenge: she needs to survive the man who knows her darkest secret, all while keeping her heart safe from the one person she is destined to destroy.
