The story deals with a plant monster that is ultimately revealed to have formed around a human skeleton, specifically that of Roger Kirk, in a swamp. P. Schuyler Miller described "It" as "probably the most unforgettable story ever published in Unknown. "Cover title reads This is "It" - Only One of the Thirteen Great Stories in THEODORE STURGEON'S New Book|from the Prime Press——WITHOUT SORCERY|Presented (Without IT's Illustrations) to THE TORCON." The 29 [Currey] leaves are printed one side only. Fewer than 200 (maybe as low as 50) copies printed. OCLC: 19372331, which states 30 leaves and two leaves numbered '30' To promote Without Sorcery, Prime Press published the story "It" in advance of the full collection. The book was published in paperback in an edition of 200 copies OCLC 19372331. 50 copies were given away at the Associated Fantasy Publishers party at the 6th World Science Fiction Convention and most were signed by Sturgeon.
