"I may have been a whole damn mess, but I was a whole damn mess on a mission." Half-succubus attorney Lily Knight has blood on her hands. Haunted by guilt, behind on her rent, and facing professional disgrace, Lily must figure out how to survive in the wreckage of her former life. To make ends meet, she accepts a contract job she never wanted but can’t refuse—hunting another demon murderer. This time, the victims are human, and a shadowy government agency will reward Lily with a way out of her dire financial straits. If Lily doesn’t solve the case before the news gets out, fear and hatred will put all demonkind at risk from the proverbial torch-carrying mob. But when a young succubus on the run from the authorities begs for her help, Lily faces a new conflict of interest—especially after the suspect, Eve, reveals her father is Lily’s old frenemy. Now Lily must juggle the pressures of a high-stakes murder case, her complicated relationship with her “not-boyfriend” Sebastian, and responsibility for a wayward teenager as she races to find the real culprit. When her investigation brings her face to face with an ancient, implacable entity fixated on bloody justice, Lily must reckon with her worst fear: the truth about what went down with Eve’s father in the desert—and its consequences.
