A well-told, gripping history of the years between 1939 and 1941 when Great Britain and Winston Churchill were the only barrier between Hitler and total domination of Europe.  During that period there was a violent clash in the US between those who would help England and even enter the war, and the isolationists in Congress and in US business.  Three men worked in London to help Churchill move FDR towards intervention—John Gilbert Wynant (Former NH governor, first head of Social Security, liberal Republican and internationalist), Averill Harriman (polo-playing failed investor but Board Chair of the Union Pacific Railroad and political wannabe), and Edgar R. Murrow (late 20-something journalist who invented radio reporting).  Winant who replaced Joseph Kennedy, an appeaser as US Ambassador. Harriman who was the Director of the Lend Lease Program and Morrow reporting nightly on CBS were close to Churchill.  Harriman had an affair with Pamela, Winston’s daughter as did Morrow)  Winant had an affair with her daughter, Sarah and influenced FDR, Harry Hopkins, and US public opinion, but the war would have gone the wrong way had Hitler not attacked Russian and Japan not attacked Pearl Harbor.  Fascinating vignettes of Eisenhower and the other generals and moving portraits of Londoners’ courage during the Blitz and the V1 and V2 attacks.  Excellent book.
