My mother bought me a good stack of these Cornerstones of freedom books when I was a young teenage girl, since I loved reading and history. I have used them many times for history projects over the course of my middle school and high school years. I have read this installment multiple times, and have found it to be a good source of historical knowledge! There is a lot of text in this book to give the reader a general knowledge of the history behind the subject. I do recommend this book, and the others in this series for anyone who loves history, and to teachers!
