I am always interested in history, and this book is a collection of mini-biographies about people who served during WWI. Some very well known names, such a J.R.R. Tolkien, Ernest Hemingway and Harry Truman to famous, but not as well known people, such as Irene Curie (Marie Curie's daughter) and Buster Keaton (silent film star). I learned a lot about these people and the actual war, which I believe is losing its place as "the war to end all wars," because so many young people really don't know much about it. Highly recommend.
