The very first book in R.L. Stine's popular Goosebumps series was published in 1992. Decades later, there are more than 30 books in the series, as well as two feature films (the latest, Goosebumps 2: Haunted Halloween, hit theaters on October 12th) and a television show inspired by the books. These thrillers are equal parts spooky and funny, with each book featuring different main characters and many twists and turns.
