Query: great surprise!!

My first book by Ablow was a great journey through some sick and twisted minds that this book has to offer. Every character is flawed in one way or another which makes the whole cast very interesting. The plot is not too complex, however within the first few pages you get sort of 'sucked in' into the story and it's very hard to stop reading. I was reading this book until the early hours because I simply couldn't put it away. I would appreciate a little bit more character development. I still have no idea how old Clavenger is or what he looks like (maybe I have missed it). Overall, Great book from cover to cover. Will gladly purchase the other books in the series.
