Query: One of the worst books I've ever read.

Without a doubt this is one of the worst books that I've ever read. The writing is poor, the plot weak. As I read this book I found myself continually trying to figure out where this particular paragraph fits into the story. It's as if the author didn't know how to tie thoughts together so he didn't even try.I see from another review that the two main characters were from previous books, and perhaps reading those would have helped with some background on them.But even so I find it hard to believe that knowing their background would have made the book any more enjoyable.Many times I set the book down thinking I would just throw it away, but I'm very persistant and kept reading thinking that the book HAD to get better. Unfortunately it didn't.The book ended and I was left trying to figure out what happened. In the end I got nothing out of this book but lost time.
