Query: The best among its kind

I can't believe there is only one review for this great, great book. Absolutely the best I've read among its kind. I borrowed a copy from a friend, but after I finished reading chapter 4 and was able to pull off a good query letter, I bought my own copy. Much better than "The Sell You Novel Tool Kit", which didn't help at all.A must-buy for any writers seeking publication!
