#15: "The Struggle For Mastery In Europe" by A.J.P. Taylor

First read this years ago -- now, reading for pleasure rather than school, it's a delight. A calm, reasoned history of European diplomacy between the 1848 uprisings and the end of World War I, it's justly noted as an all-time classic. Not much I can really add about it, if 600 pages on 19th century maneuvering sounds good to you, you'll love it (and have probably already read it). I've got a few more Taylor books stacked up already.
