It might be mainly about three key players of the Second World War, but I think every person out there should read The Stalin Affair. It is a terrific read about the art of compromise and how people often put up with one evil in their endeavour to defeat another. The book also gives us a look at three major leaders of the Second World War - Stalin, Roosevelt and Churchill - and how they viewed each other. History buffs will love this, and so will general readers (it is so much fun to read). Pretty much a must-read for everyone, in my humble opinion, and at about 400 pages, not too heavy either.
