Probably the best general history of WWI that I've read. It covers all the relevant topics (pre-war situation and concerns, politics, technology, strategy, tactics, art, post-war settlements, etc. etc.) and at a reasonable depth and thoroughness. Side topics are interleaved through the main history at relevant points, and overall it gives a clear and comprehensive overview of the war. I kind of want to write more in this review, but I'm not sure what else to comment on as the book is just a completely solid effort from start to finish.
