It was life as usual for half-Demon Avery Tywella when she chases a Demon convicted of murder into a local club. As an agent of the Human's Rights task force, it is her duty to execute any Other proven to harm Humans. But her actions in Halo attract the attention of Jared Damascus, the lead singer of local rock band sensation, Darkened. And, a night of clubbing with her friend leaves her with unwanted attentions from, not only, a Fallen Angel but a psychotic murderer.

Now, with a Fallen bodyguard at her side, she has to find a crazed killer before he strikes again. The only problem is convincing her Fallen admirer to let her do her job instead of protecting her. Because she is going to need the help of him and his band of vigilante crimefighters to take out this crazy Angel so she can get back to her life before she does something she regrets with a certain hot rock star.
