Nightmare Inn is a series of young adult horror novels by Todd Strasser, who penned the books using the pseudonym T. S. Rue (another pen name he sometimes uses is Morton Rhue). It is a brief series that contains only four installments, all of them published in 1993; the books were distributed by HarperCollins, who released them in both paperback and hardcover editions. Nightmare Inn is not only the official title of the series, but is also the title of the first book. The remaining novels are titled Room 13, The Pool and The Attic. The books were published in the same time period in which R.L. Stine was enjoying phenomenal success with his highly popular Fear Street novels, but Strasser's saga was short-lived; whether this was the intention of the author or the result of poor sales is unknown, but the entire series has been out of print for many years. HarperCollins included the books in its Nightmares series, a group of novels that have no relation to each other besides their themes of horror. Nightmare Inn, The Pool and The Attic were published in an anthology called Nightmare Inn: Three Books In One. Source: Wikipedia (en)
