Charlie and the Great Glass Elevator (1972) by Roald Dahl is the sequel to Charlie and the Chocolate Factory, launching the Bucket family—Charlie, Grandpa Joe, and Willy Wonka—into a zany space adventure. After the chocolate factory takeover, Wonka’s glass elevator accidentally orbits Earth, where they encounter the hostile Vermicious Knids (alien slug-like creatures) and bungle a visit to the U.S. president’s space hotel.
Dahl’s signature wit and wordplay shine, though the plot’s absurdity lacks the first book’s charm.
