A Night in Terror Tower is the twenty-seventh book in the original Goosebumps, the series of children's horror fiction novels created and authored by R. L. Stine.

After they leave the hotel's restaurant, the man in black blocks their path, and sends them to Medieval times with magical stones.

In the dungeon, the children meet Morgred, a white-haired sorcerer, who informs them that they are Edward and Susannah, Prince and Princess of York, heir to the throne, and niece and nephew to the current King.

After being asked by the children, Morgred refuses to send them back to the future, fearing for his own life, even after Eddie hands him the three magical stones, which he had stolen from the Lord High Executioner upon his capture.

Jeffrey Kauffman, of DVD Talk, wrote, "If you're new to the Goosebumps world, this is a great place to start, with two exceptional episodes which perfectly balance thrills with an at times black humor".
