Simon Green is not the best urban fantasy author out there, but he is certainly one of the most consistent. His Nightside, Ghost Finders and Secret Histories novels are rarely astounding, but are always entertaining, fast and fun. This, the tenth Secret Histories novel, is no exception.
First, the downsides. This book is basically just a series of side-plots stitched together to novel-length. The main story (Eddie Drood is poisoned, and must hunt down his murderer) is abandoned very quickly for a wild goose chase for a cure. It isn't until the tail end that the chase for the culprit is resumed and, though the result ties in beautifully with series lore, the final confrontation is perfunctory at best. I don't have issues with the cliffhanger ending, though others do. I just didn't like that the final battle was relegated to the last 4-5 pages of the book.
On the other hand, the characters in this series are still a lot of fun, and the subplots are all fascinating. It does get a little mopey and heavy-handed at times, but the quick pace means you'll be out of the doldrums before major frustration sets in. The action sequences are swell, as usual, and the humor is on point.
All in all, this is a solid entry in a solid series. If you're a fan of Green, this is a perfectly decent place to get your kicks. Just don't expect anything life-changing.
