The Throme of the Erril of Sherill is a fantasy novella for juvenile readers by Patricia A. McKillip, as well as a subsequent collection containing the novella. The novella was first published in hardcover by Atheneum in 1973. It bears the distinction, along with The House on Parchment Street (also 1973), of being one of McKillip's first published books. The novella was later gathered together with the author's short story "The Harrowing of the Dragon of Hoarsbreath" into a paperback collection, also titled The Throme of the Erril of Sherill, issued by Tempo Books in January 1984. The collection was reprinted in February of the same year. Source: Wikipedia (en)
