Query: The best book in a long, long time

This is an incredible book. It's funny, irreverent, brilliant, amazing. This author has the kind of natural voice that makes other writers want to chuck their pens. I couldn't read the book fast enough, yet I didn't want it to end so I had to pace myself, allowing only a few chapters at a time. By doing this, I was able to make the book last, hmmmm.... around four hours. I just had to read it fast. (Also, this is a great "writers' writer" book, i.e., if you're a writer, or you want to be a writer, or you used to be a writer, or you're a really bad writer, this is a have-to-have.)
