Hard to beat for me is, Lee Miller's War, - the photographs and writings of a civilian war correspondent following the US troops from St Malo to Munich and Dachau.
Don't be put off by the fact that Miller's reports and pictures were first published in Vogue, or even that Miller herself had once been a Vogue model.
The book is full of Miller's iconic photography which are definitive images of WW2 and have shaped a score of war films. Including the famous picture of Miller in Hitler's bathtub on VE day.
