It's amazing.
The story is fast paced without losing the reader, the idea behind it is fabulous (I still need to get to the end to see 'why he dunnit' but this book's definitely worth the money I paid for it!
The fact that I am so close to the end of the book and I still don't know the antagonist's motive is a big feather in the hat of Mr. O'Malley.
Just wanted to let you all know.
