Query: What happened to read all night!

I am very disappointed in this book. I expected a can't put it down read as with his other Alex Cross books. Usually I finish within three-four days but this one took me over a month. I couldn't wait to finally read a book he had written by himself once again but with this one I could of waited until it came out in paperback...Judge for yourself...
