Query: Only product that I wanted to return.

I was really surprise on how much I hated this book. Everybody talks wonderful things about it and how it has change the view of childbirth. It might have, but the book is poorly written and really depressing. I tried to returned it but Amazon said that I could keep it (I guess it was cheaper to give it to me than to return it)... I wish it was a better book to keep!
