"You'll win every bet with that coin." Jessica Bowen and her best friend, Ryan Chang, really enjoy magic tricks. They find the perfect HorrorLand souvenir in Jonathan Chiller's gift shop — a two-headed coin that ends up having mysteriously dark powers. After an unlucky flip of the coin, Jessica and Ryan find themselves transported in to a world of terror. They find themselves back in time, being chased by angry guards who accuse them of beheading the prince. Unless they can avenge the Prince and reunite him with his head, their own heads will be on the chopping block! HorrorLand was scary but this is much worse. Will they be able to escape with their heads still attached? Every book in this seven-book HorrorLand story arc 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!
