Query: Not for somebody with a short attention span

I really didn't like this book. It's very long and wordy, and it describes things of no importants. Henderson goes off in long stories that mean nothing, and then expects people to remember what he was talking about in the first place. I guess if you like books that have first person narratives and long stories, you'd like it. But if you want action and suspense, this is NOT the book for you.
