This little book hits the spot for preteen & older readers. It's graphically colorful, with a variety of interesting photos & illustrations; it's written conversationally, yet with enough factual citations to validate the unbelievable, heroic stories; and, it introduces the reader to a cast of amazing female characters mainly unheard of in contemporary American culture.I bought it to send to my grandchildren, but was captivated into reading it myself. I learned a lot.
