Bo Blackman is a first year private investigator working for the London-based firm Dire Straits. She doesn’t often get triber-based projects, which is just as well. Vampires and daemons don’t curiosity her just as much as humans do.

However, when she has to serve a summons on a dodgy daemon called Devlin O’Shea and she eventually ends up saving his life rather than being framed for his murder, her life takes a shocking switch for the worse. And when the vampire Households start regarding themselves as well, Bo no more knows where to switch.
