Making History by Stephen Fry

Stephen Fry tackles alternate history, What if Hitler had never been born?
 Michael Young is a graduate student at Cambridge who is completing his dissertation on the early life of Adolf Hitler. Leo Zuckerman is an aging German physicist and Holocaust survivor. Together they idealistically embark on an experiment to change the course of history. And with their success is launched a brave new world that is in some ways better than ours—but in most ways even worse. Fry’s sci-fi-tinged experiment in history makes for an ambitious and deeply affecting novel.
