Kinsley Adams can't deny the growing darkness within her as a result of being branded by Lucifer's Star. It gnaws at her, pushing back her humanity as it grows. The only way to beat not only the darkness, but also Lucifer, is to find the Book of the Guardians. Problem is, she nor her guardian angel/former golden boy, Joshua Stone, know where it is, until a source comes forth and reveals that the ancient book of angels is located in Paris. Kinsley and Joshua must hurry to find the answers they seek before the darkness conquers whatever humanity is left, and all hope for salvation is lost.
