James Blish

James Blish wrote many novelizations of TOS. He was the first to do so under Bantam Books. He adapted every TOS episode into a short story with the exceptions of "Mudd's Women", "I, Mudd" (which he intended to write as novel-length stories, later finished by his wife as Mudd's Angels and printed in 1978), "Shore Leave", and "And the Children Shall Lead" (he died before he finished these stories). These novelization were printed in 12 popular mass-marked paperbacks, titled Star Trek, Star Trek 2... etc. all the way up to Star Trek 12. He also wrote the first original Bantam novel, "Spock Must Die."
