Query: There is no middle ground with this book!

I think it is important for people to know that you will either love this book or hate it. I know of about 20 people who have read this (including a women's book club) and most people loved it. However, the people who did not like it (mostly in the book club), had little good to say. If you look at the reviews, they are mostly 5 stars and the few 1 stars.If you are open, like a little dark humor and appreciate good writing this book is for you. Let's just say, it will keep your "valve open".
