Really good. First sparked interest in the Great War by visiting the World War I museum in Kansas City. Does a really great job at tracking the impetus behind the conflict and the inner workings of the military brains in the Central Powers and Allies and detailing battles, lines and movements.

Barely hints at the air force battles and the use of gas. Does not go into life in the trenches or generally how the actual battles, space affected the civilians of France, Belgium, Africa or Turkey. This is for a military historian more than a person seeking a personal look at the war. Still very good though.
