Alan Brooks. London at War: Relics of the Home Front from the World Wars. Barnsley: Wharncliffe Local History, 2011. What's left? More than you might think -- shelters, bomb damage, memorials (lots of those), even ghost signs. Profusely illustrated.

Zara Steiner. The Triumph of the Dark: European International History 1933-1939. Oxford and New York: Oxford University Press, 2011. With the first volume, The Lights that Failed (which I bought almost exactly six years ago), Steiner has produced the definitive history of the international politics of interwar Europe, at least for a generation or so. Although page 88 could have been improved with a reference to recent work on the British air panic of 1935 :)
