Query: Revenge: None in this book!

I picked up this book in the super market, ready for a good book of wit and fun. What I got was a long, depressing book of life. There are lots of things with middle age we can all laugh about, and I thought this would be a book of them. However, it was only sadness. We get enough of real life, please pass on this one.
