In this outing, there's a paranormal/supernatural conference in London and Kitty is the Keynote speaker. The guys at the station get her and Ben a first class upgrade and Tyler joins them in London. They are staying with the Master (vampire) of London, Ned, and his protege, Alette's descendant and newly-made vampire. The main storyline is European vampire culture and its relationship to weres, and Kitty's efforts to directly address the problem of Roman/Dux Bellorum and The Long Game.
I wouldn't start with this book, but the series continues to entertain and offer up paranormal analogues for real-world hot buttons. I'll keep reading. I like how Cormac/Amelia really get an opportunity to develop as people -- not just characters -- in this episode.
