Gonick wraps up his History of the World series in this volume, and a worthy wrapup it is. Gonick continues to use the flair and accessibility to keep history from becoming dull and dry. The art pops and the voice of the author is present without being overwhelming.
I do have one minor quibble with the book, and that is that Gonick occasionally is a bit too close to some of the last history. As we get closer to the end of the book, we start seeing more of the events of history through the lens of the 2000s, when the book was written. This is unavoidable to a certain degree, but it is a bit jarring, even read now, a mere four years after publication.
This really is a fantastic series. This probably isn't the book you should start with, but it will do an excellent job if you're looking for a very high-level understanding of the last 225 years of history.
