Dreadnought is a fantastic read.. My wife has recently become interested in the “war to end all wars” and I keep placing this behemoth of a book next to her phone..
George, Nicholas, and Wilhelm Three Royal Cousins and the Road to World War I
Massie’s “Dreadnought” is an excellent book. Other pretty good reads on the origins of World War 1 are David Hermmann’s “The Arming of Europe and the Making of the First World War” and David Fromkin’s “Europe’s Last Summer.”
Both of them pretty much lay the blame for the war at the feet of Helmuth Moltke, as he saw the war as Germany’s last chance to dominate Europe before the Franco-Russian allies surpassed Germany and a declining Austria-Hungary.
BETWEEN THE WARS is another great book, that you and/or your wife might be interested in.
