The Plot Against America, by Philip Roth.
Roth’s novel is a compelling, inspired work—imagining what life might have been like for America, and for American Jews (with a particular focus upon one family from northern New Jersey, the Roth family, and its youngest son, Philip), had Charles Lindbergh become President of the United States, in 1940. It is a superb novel, by one of America’s finest writers.
