“Alternative history”. Fantastic assumptions on the topic “What would have happened if...” If Alexander the Great had not died at such an early age... If Napoleon had not lost the Battle of Waterloo... If Hitler had won the Second World War... For a long time - one of the favorite genres of world science fiction! The genre in which Harry Harrison and Robert Silverberg, Paul Anderson and Philip K. Dick, Michael Moorcock and Sprague de Camp worked... All the great masters of “alternative history” cannot be listed. But the works included in this collection are rightfully recognized as classics of the genre!
