Query: One of the most poorly written books I have ever read.

Wow. Never before have I been so angry after finishing a book. It has as its subject an intersting case but seems to have been written by someone in grade school. The same limited information is repeated over and over and over again-- some paragraphs were even repeated verbatim throughout different chapters. I'd spoil it by giving away the ending, but there isnt one. If you see this book the only rational thing to do is burn it.
