Jessica Bowen and Ryan Chang bring home a two-headed "joke" coin from the HorrorLand souvenir shop. A simple coin toss transports them to a world of terror. They find themselves back in time, being chased by guards who accuse them of beheading the prince. Unless they can avenge him and reunite him with his head, their own heads will be on the chopping block!

Start the summer the Goosebumps way, with the third book in the newest seven-book HorrorLand arc. Every book begins in the HorrorLand Gift Shop, owned by Jonathan Chiller, who invites unsuspecting kids to "take a little horror home!" Little do they know what terrors await them!
