Publisher Jim Baen joins two of his top authors to collect the stories which made them SF readers in their youth and fitted them to make major impacts on the SF field today. The quality of the stories in this huge volume compares favorably with that of any collection in the past fifty years--there''s been nothing of equal size and quality since Groff Conklin''s Omnibus of Science Fiction in 1952. Nevertheless the selection wasn''t through some would-be objective standard but rather by a deliberately subjective process: these are the stories which, when the editors read them, turned their worlds around. Each story was picked because of the emotional charge it gave one or more of the editors on first reading. The story sources range from Analog to Weird Tales, the first appearances from the early ''30s to the mid ''60s. Many were written by the greatest names in the SF field. These are stories that made the editors think and feel. They will do the same for you.
