I listened to this in audiobook form, which was a mistake in retrospect because it's so tightly packed with details and facts that being able to flip back and forth - not to mention refer to maps - would have been much better. Nonetheless it was a detailed and generally interesting analysis of all the causes and factors of World War I, ending at the close of 1914.

Why and how the Austrians and Germans encouraged the call to war, how other nations contributed, the early decisive battles, and some of the terrible mistakes. Fragments of letters and personal diaries from participants makes it more personal and poignant.
