I absolutely love these dermaplaning razors! The stainless steel blades feel sturdy and high-quality, giving me confidence every time I use them. They work amazingly well, effortlessly removing peach fuzz and dead skin without causing irritation. After using the razors, my face feels incredibly smooth and refreshed, like a mini facial at home. I appreciate how easy they are to handle and how precise the blades are, making dermaplaning simple and effective. These razors have become an essential part of my skincare routine, and I highly recommend them to anyone looking for a reliable and gentle dermaplaning tool.

Format: Kindle
Trying to distill WWll down to a little over 400 pages is a Herculean task but Mr. Kennedy does a serviceable job. He provides thumbnail sketches of the major players' personalities and tics. He does an admirable job of jumping back and forth between the European and Pacific theaters of operation, always keeping in mind America's POV in explaining how FDR and his staff dealt with their fractious, troublesome allies. He explains how the Rosie the riveter myth is pretty much a fabrication and how America's approach to manufacturing was able to out produce the German mode of war production: America going for Quantity vs. the German fixation with Quality. Lots interesting information and facts. There are areas where I thought he could have used more depth such as the death of FDR (probably no more than two pages.if that); Mussolini and Hitler's last hours are given mere paragraphs; Churchill being voted out of office just months shy of victory in Europe is given maybe two paragraphs and while he mentions how Tibetts went to the airplane factory to pick the future Enola Gay off the assembly line he gives short shrift the immensely expensive and technically complex challenge of building the A-bomb. Nor does Mr. Kennedy mention that when HST hinted to Stalin that America had an powerful new weapon Stalin was all ready aware of the activities going on at Trinity and of the Manhattan Project. Mr. Kennedy doesn't offer any new information or insights but this is a good, one-book overview, of the war.

Thorough But Easily Read Historical Account
Format: Paperback
I bought this book thinking it would be an account of civilian life in the U.S. during WWII. But I was surprised to see that it focused almost exclusively on the military campaigns and the decisions behind them. There was sporadic mention of life on the homefront, but mostly the book is a book about the war. Which is not a criticism. Kennedy deftly and thoroughly takes us through the war, outlines for us the challenges and opportunities and how the leaders of the affected nations developed their strategies. In addtion to the fine details of history, Kennedy writes in such a fashion that this book will probably appeal to the scholar and the layman with equal strength. As someone long in the tooth, I knew most of the history of WWII, but if you are younger and want a comprehensive, well-written history an epic period in world history, you could do a lot worse than read this compelling book.
