has she seen "The Mantle of Command" by Nigel Hamilton? Came out earlier this year from Houghton Mifflin. Full disclosure -- my wife was copy editor.
The sub-title is "FDR at War, 1941/42." Along with everything else that happened in that period, Hamilton really gets inside the relationship between FDR and Winston Churchill. Real eye opener for a Brit like me!
Proper job . . research, original documents, yada yada -- definitely not the Fox or MSNBC version!
