Dire Straits- Helen Harper

Bo Blackman is a rookie private investigator working for the London-based firm Dire Straits. She doesn't often get triber-based assignments, which is just as well. Vampires and daemons don't interest her as much as humans do.

However, when she has to serve a summons on a dodgy daemon called Devlin O'Shea and she ends up saving his life instead of being framed for his murder, her life takes a shocking turn for the worse. And when the vampire Families start involving themselves too, Bo no longer knows where to turn.
