The war between Heaven and Hell has been reignited, and Riley Parra is caught in the middle of it.
Following Riley's actions during her trial, the battle between Heaven and Hell has been reignited. Riley barely has time to recover before she’s thrown into the middle of a serial killer investigation. Dubbed the Angel Maker, the killer strikes seemingly at random and uses his victim’s blood to paint angel wings around the body. While Riley tries to track down the killer, she also has to try and identify her counterpart, the champion chosen to represent the side of evil.
In the course of her investigation, Riley is forced to confront everything she once believed, from her own sanity to secrets being kept by her closest friends. With the help of her seraphim partner, Caitlin Priest, and her human partner, Gillian Hunt, Riley rejoins the battle between angels and demons with only one goal: to keep herself and her friends alive.
