Query: an unexpected pleasure

I first picked up this book because it had an interesting title. On a pure whim I read it and enjoyed it more than I have any book in years. It was refreshingly funny yet it has substance that kept me interested. I couldn't put it down. I have told everyone I know that enjoys reading to get this book. It is sharp,funny and a sure cult classic.
