Hello!
I am currently looking for a book that will cover the history of WWI. I've been looking for this answer online but most of the books that I find people suggest only focus on a part of WWI, for instance, The Guns of August sounds interesting but only covers a certain period. I would prefer something that begins with the events that led to the war and ending with the aftermath. One of the books I've found that may fit the bill is A World Undone by G. J. Meyer, but I'm not finding too much about it yet.
Thanks!
The subreddit has a list of suggested books about WWI for you to peruse at your leisure. It reflects the influence of /u/NMW.
