Thunder at Twilight

Bens highly recommends reading Thunder at Twilight by Frederic Morton. Check out the Amazon reviews; it received 5 stars from the reviewers there. Here is a short snip from one of the reviews:

In 1913 Vienna was host to men who would make an indelible impression on the 20th century. Just to name a few, Lenin, Trotsky, Stalin, Hitler, Tito, Freud, and the Hapsburg Royal family all within one square mile of each other. Morton gives a good portrayal of the lives of these men during their formative time spent in Vienna. He also gives a good account of the tension between Arch Duke Franz Ferdinand who wanted to reform the Austro-Hungarian Empire to include the room for nationalist aspirations of the Slavs, and Emperor Franz Joseph who wanted to maintain the status quo.
