Written as an introduction to major world history events, Hugh Williams' 'Fifty Things You Need to Know About World History' explains the importance of historical events upon current society. As a novice of world history, I appreciated reading about a number of topics that I was not aware of, particularly to Asian events.
As with any topic that requires a bit of buy in from the reader, a skilled author makes the heavy lifting less burdensome. Unfortunately, Williams writes a rather dull account of some otherwise interesting and even exciting events. The only humor I encountered during the reading was the sprinkling of personal opinion made fact and the faint but detectable pride in his British nationality (and thus very mild repugnance of the United States' events or discoveries).
For the price I paid ($1), I'd give it four stars. At full price, I give it three.
