In the midst of an emerald green sea lies the Land of Halloween—an island that can only be visited in dreams. Full of year-round adventures, thrills, and chills, it is open to children from all countries where Halloween (or some version) is celebrated. They come to trick-or-treat, play games, and compete for prizes. But only one child or team can win the Grand Prize: First-class tickets to travel anywhere in the world for two years. For Olivia and Hailey Devant, this would be a dream come true—and they’ll do everything they can to win!
