This was a very good, action packed urban fantasy adventure. It had the usual mix of vampires and werewolves, all with interesting characters, but also introduced the golems which was something a bit different. Jace has a wise cracking golem bodyguard called Charlie who was my favourite character. Jace herself is tough and I liked her, especially the fact that she makes mistakes and wrong decisions like everyone else.
It was interesting for the human to be stranded in a world where she is in the minority and in constant danger. I also liked the way the people of the two worlds were fascinated by each others technology and strange ways. The book cleverly mixes our world history into a supernatural context ie what happened to vampires and werewolves in Nazi camps. A good supporting cast kept this book fresh, good action, good humour and I really look forward to reading book 2.
