Goosebumps HorrorLand

Goosebumps HorrorLand is a horror novella series by R.L. Stine, a spin-off of his popular Goosebumps books. There was an almost ten-year gap between the publication of the initial installment in the Goosebumps Horrorland series and the previous publication of other Goosebumps novels.

R.L. Stine is currently writing what was originally announced as a twelve-book series titled Goosebumps HorrorLand. The series, based loosely on One Day at HorrorLand (sixteenth in the original series) and Return to HorrorLand (thirteenth in the Goosebumps 2000 series), is the first Goosebumps series where each book is part of the same plot, and the first Goosebumps fictional crossover, with characters, villains and locations from distinct Goosebumps continuities interacting.

The first twelve books were announced with the following details:

The new series will be an immersive storytelling experience welcoming fans to HorrorLand, a vast theme park which R.L. Stine describes as “the scariest place on Earth.” In a Goosebumps first, the new series will be a serialized adventure, and the story won’t end on the final page of book one, Revenge of the Living Dummy. Instead, the spine-tingling and funny bone-tickling adventures will continue on the Internet and in books #1-12, each of which can also stand alone. The first nine HorrorLand books all will feature a combination of frightful new faces as well as the vilest villains from the original Goosebumps series. Ordinary kids are being summoned to HorrorLand—but why? Readers are in for the ride of their lives as the cast of characters trapped in the theme park grows larger with each book, and their situations become more and more perilous.

Books #11-12 will take place entirely in HorrorLand. Who—or what—is behind the evil plot to assemble these kids? The answer will be revealed in the final book. Soon after the debut of books #1 and #2, Scholastic also will begin to reissue original Goosebumps books—ten bestselling titles that tie in with each new story as it unfolds in HorrorLand.

Each book had two stories. The purpose of the first, considerably longer, story is to introduce the villain and protagonists; the second story shows what happens to the protagonists when they get to HorrorLand, and are united with the other characters. The books also include a case file that links to material on the EscapeHorrorLand.com tie-in website. The final two books in the series serve to wrap up the 'HorrorLand' plot in a single climactic storyline.
