To be honest I was a bit dubious about this book at first, until I started reading it that is. People of my generation studied World War 1 at school, so have an extensive background into the subject, and also in my case our school did also take us to the Imperial War Museum, which also helped a lot in understanding what it was like to live and fight in the trenches.
This book tries to gather the main points together into something that will take you about an hour to read, also including appendices and photos. All in all this does actually do a great job of this. It shows how the war started and the reasons, as well as the main countries involved. Where else this excels is how it shows things being inter-connected, such as the Easter Uprisings in Ireland, the revolution in Russia, and how such countries as Israel started to be created. Of course this would not be complete if it didn't show the world how it was after the war and some of the reasons for the next World War.
This is ideal for anyone wanting to brush up on the First World War, and I would say that this is excellent for anyone having to study this for history and would be ideal for school children. With an active table of contents and the inclusion of photos obviously a lot of thought has gone into this.
