This wasn't great- the writing style and the author using himself as the protagonist of his fictional book was just kind of weird. And the story itself felt like it dragged. It was an ok mystery, and wasn't predictable, but none of the characters caught my interest. I personally am not a fan of the narrator of the audiobook, although that preference doesn't affect my rating in this case because it didn't affect my opinion or enjoyment of the book. 
All in all it wasn't bad but I'm not glad I read it and I probably wouldn't recommend it.
