Review title: AN EXCEPTIONAL WORK Product review: This volume is a major contribution to the history of the Luftwaffe during the Russo-Germano war. "Stopped at Stalingrad" is also a richly drawn study of the most important air campaigns in the Eastern Front. Written in an accessible style this volume will be welcomed by anyone with an interest in the WWII. I was very pleasantly surprised by the book and also the quality of its contents. The author did a masterful job of research. Joel Hayward draws on diaries of both key commanders and regular airmen. He also shows that the poorly conceived strategies of Hitler and his buffoon, Goering, dommed the efforts of men such von Manstein, Milch and Wolfram von Richthofen (an outstanding soldier) to come to grips with an impossible situation. I heartily recommended this book.

Product review: I'm shocked. It really worries me that so many girls my age read these books. I don't like to sound like a parent, but these books set a really bad example. The characters are so spoiled, it's disgusting. And they're mean, not to mention slutty. How can this book be a bestseller? It's trash. Don't people get bored with girls acting trashy and sleeping around? Look, read what you want, but parents should be warned about this book. Gossip Girl is a serious waste of your time!!
