World War Two, A Short History, by Norman Stone, is a not-too-difficult history of what will hopefully be the last world war.
It’s sometimes too detailed for me, and more maps would have been helpful, but at 200 pages it’s a manageable explanation of the complex story of this devastating war.
The book does an excellent job of portraying the monumental scale of the conflict and the enormous devastation and loss of life. Recommended.
