Juster's friend, the children's author Mo Willems, said on Twitter that Juster "ran out of stories & passed peacefully last night." "Norton's greatest work was himself: a tapestry of delightful tales," Willems said. "The Phantom Tollbooth" tells the tale of a bored young boy, Milo, who is transported to a world of wonder when he drives through a magical tollbooth that has arrived without warning at his house.
