What if? has been, for the most part, the domain of science fiction writers, and Harry Harrison was first and foremost a Science Fiction writer. But history often turns on a fulcrum and what if that delicate balance tipped in a different direction? What if Hitler had died in prison before Mein Kampf was released? To write such a novel--or series--succesfully an author must be well steeped in the events of the day to make a believable series of alternate events. Harrison veered from heroic science fiction into this world later in his career, forging a path that few have had the strength to walk along.
