I've been a fan of Simon Green's books for quite a few years. He writes some of the best villains around, and his heroes are bold, snarky, funny and prone to violence. His books are just absolutely reliable if you're looking for a good adventure in a vividly described world.
This particular installment of the Secret Histories series had some of the best characters from some of his other series including Bruin Bear and the Sea Goat. If you haven't read many of his books and series, they are recurrent characters who have been in both his fantasy and science fiction books. There is also one of my favorite characters from Nightside.
This book had a lot more pop culture references than usual. I think in one case, he repeated a joke from a previous book. It was still a lot of fun and the references fit Eddie Drood's character. One American tv show reference had me laughing so hard that I had to explain myself to my daughter. Molly Metcalf is one of the best female characters he's ever written as a love interest. This series is also notable because there is a fair amount of character introspection, but it's paced well with lots of action filled scenes that are meticulously described.
I do recommend starting at the beginning of any of his series. They can stand alone, but they are much better with back story.
If you like really fun action filled cross genre stories with fantastic elements, these fit the bill nicely. I think it would make a wonderful tv show, movie or comic book as well. It has that kind of feel to it.
