Laurell K. Hamilton got famous when the author started writing stories about demons and vampires. The series about Anita Blake was the best that the author created over the years and now this one is a new series in which the audience gets introduced by another detective named Zaniel Havelock. The man like the characters in Death of a Darklord and Crimson Death has a strange kind of power i.e he can talk to the angles.
Being a human this is a unique kind of power that he has been blessed with so he started helping both the angels and the humans. A tragedy changed his attitude towards the thing but Zaniel never stopped the good work.
When the introduction ends, we are told by the narrator Holter Graham that Zaniel has started working like a cop now and he is trying to hide the past which he used to live a few years back. When he is called to a horrific murder sight, he gets alarmed because it seemed that it was not the doing of a human being. Just like angels, demons also exist in the world and they can possess a human body too which can result in the such terrorizing outcome.
Now Zaniel has to stop that devil because he is the only one who can do it and in order to complete this job, he has to face his own devils which he has been trying hard to get rid of. For the sake of both worlds, the hero once again starts the battle against the devils although he is aware that he can suffer in the long run but he is not one of those who back down from a challenge.
