This tenth volume of the complete children’s sci-fi series features a time-travelling space odyssey and a spring break vacation gone terribly wrong. Norby and the Court Jester On spring break from the Space Academy, Jeff Wells and his robot, Norby, head to the planet Izz for a toy and game fair. They look forward to seeing Princess Rinda and her little robot, Pera. But when Norby receives a telepathic message from Pera—part of which is “help!”—Norby and Jeff are sure that trouble awaits. And whatever’s going on, it’s most likely thanks to the evil Ing, the new Court Jester on the planet Izz. Norby and the Terrified Taxi In an adventure that changes the course of Earth’s history, Jeff Wells and his robot, Norby, are catapulted through time and space to find a dangerous and bad-mannered prankster, Garc the Great. In their search for Garc, Jeff, Norby, and their colleagues are trapped by a powerful alien Connector Ring. Now all they have to do is escape, find Garc, save the human race, and return to Earth in the correct time frame!

While visiting the toy and game fair on planet Izz, Jeff and Norby search for a missing robot and the villain responsible for sabotaging the planet's computer system.

A Space Academy student and his time-travelling robot stop an evil villain from taking over the Solar System in this children’s sci-fi classic. Fourteen-year-old Jeff Wells, a cadet at the Space Academy on Mars, is in danger of being kicked out unless he can improve his grades. With a little help from the academy’s commandant, Jeff finds a robot named Norby to help him study. But Norby’s no ordinary robot. He has the only mini-anti-gravity device in existence. Norby’s special abilities suddenly come in handy when a villain named Ing targets Jeff’s older brother in his quest to conquer the Solar System. When Ing takes over Manhattan Island, renaming it “the Kingdom of Ing,” Norby and Jeff put studying aside to teach Ing a lesson!
