Review title: As much fun as reading an outline. Product review: I was disappointed in this book. The cover art is inviting, but the prose is dull and predictable. I am a WWII buff, but I started looking forward to the next book on my to-read list a dozen pages into this tome. Historical figures like George Patton, Churchill, Eisenhower and Irwin Rommel deserve better than they received at the hands of Jeff Sharra.

Review title: Exploring the clues to Paris's mysteries Product review: Downie's essays offers a quirky sense of humor and a wonderful eye for the details behind the details that at once demystify Paris and add to her mystery. Although the book is not a guide per se, the essays make me want to follow Downie's trails. As such, the book would have been better served with an index and some neighborhood maps. After all, give us a few more clues.

Review title: A must-have for WWI aviation buffs Product review: This is an excellent title, the best I've read on WWI aviation. Not for the quality of the writing but because the author is Manfred von Richtofen himself. It also includes chapters by his younger brother Lothar, another German ace, and Capt. Roy Brown, who is credited with shooting the Red Baron down. A great book! Hope you can find a copy. (Can't have mine :-)) Patrick Williams
