I liked this book because everybody usually thinks that bad people are men. But this book shows that there are bad women too! In some of the stories, I thought the women were not guilty, like the story of Catherine the Great. Almost all of these women came from good families, but they turned bad as they grew up. This book would be good for 5th grade to Middle School kids. If you like mystery stories, I think you would like this book very much. I give it 5 stars.
