Up until this novel, I was only familiar with Mike Carey's comic book work, primarily Lucifer and The Unwritten (both excellent titles, by the way). This is the first prose novel of his I've read, and coincidentally the first novel in the Felix Castor series.
While Felix comes off a bit like John Constantine (Carey also wrote some issues of Hellblazer), the uniqueness of Castor's universe allows you to look past a lot of the familiar occult detective tropes. Carey comes up with creative origins of the various supernatural types, some of which are refreshing takes on otherwise tired concepts. Combine that with some snappy dialog and excellent pacing, and you end up with a book that's an absolute blast to read.
If you're looking for something both fun and new, this is definitely a book to check out. Highly recommended.
Available at Amazon.com, Barnes & Noble, and Books-A-Million.
