This is a wonderful book for all ages.
I am an adult and enjoyed being introduced to women world changers I was not aware of.
I love this type of book that is geared for the young, because I can read it swiftly, then follow up afterward by finding more in depth books for adults about the individual people.
At the back of this book is a list of more women from around the world who one might want to learn about. I did that with a couple of them already and have learned a lot I did not know.
I highly recommend this book and hope you enjoy it as much as I did. If I had a 9 year old or older child, especially a daughter, I would have her read it.
I would also find this a wonderful book to have my elementary school class read with an alternate about men who changed the world, so the students would have a nicely rounded knowledge of history.
