Query: Brilliantly researched and written

Brilliantly researched and written. Canadian scholar Kazimiera J. Cottam in her Women in Air War relays to us the tales of brave women who served on the Eastern Front of WWII. While written and researched by an expert in Women's Studies whose specialty is the Russian women of WWII- this book is an easy read for all. It gives us valuable insight into the nature and courage of women we have never heard of--but should have heard of. You will read biographical sketches of women dive-bombers, night bombers, and fighter pilots. And come to know and care about each of these women and find yourself wondering why none of this information was available to you.
