Over 75 years later, the terrible events and dramatic outcome of World War II remain relevant and important, and we truly live in the world that this conflict created. Many of us, however, do not possess a clear picture of how and why the war occurred. From the opening salvos in Poland to the atomic bombing of Japan, Royal Navy veteran Michael O'Kelly provides a swiftly paced yet thorough look at the 20th century's defining event, and his book is rounded out with maps, background info, and interesting anecdotes.
