This short book doesn't have an over-arching story. Instead, each chapter tells of a sortie or raid over Occupied Europe during the Second World War.
The book follows two pilots, Squadron Leader George Yeoman of the RAF and Major Joachim Richter of the Luftwaffe, both aces, both committed to their jobs and their countries.
The author is good on the technical aspects of flying. He quite obviously knows his stuff. However, the lack of plot and characterisation lets this book down. Yeoman and Richter are practically interchangeable. There are tantalising glimpses of what could be solid plot lines, but they're just dropped in and left to lie fallow.
This book certainly gives you a sense of how exhilarating and terrifying aerial combat was during the war. It also gives you a strong sense of the terrible loss of young lives. If you're interested in the air battles and air raids of the Second World War, this is definitely worth a read. If you're here for a fully developed story, this is not the book for you.
