My favorite thing about this genre is how some basic knowledge is needed about how things actually occurred in order to appreciate how even a small alteration can result in exponential consequences. In this collection, Johnson provides detailed historical information with humor and a sharp appreciation for irony. He proposes different outcomes for a wide array of world events: from the arrival of the Vikings in North America to the Crusades to a potential thermonuclear war. The conversational tone makes this work of nonfiction fascinating, thought-provoking, and anything but stuffy.
