Query: a waste of time!

I completely agree with the critic who suggested that this book would be much better off being a long magazine article. It's boring, it drags on and is not very well written at all. If someone asked me what the book was about, I'd be able to narrate the entire story in 2 minutes and save them the ordeal of actually READING the book!This book really was a waste of my time!
