Summary: The 4th book in the funny science fiction series.
Review: This is the fourth book in the humorous science fiction series for children about a young space cadet and his unusual robot Norby. In this story, beings from another planet have invaded a planet of friendly dragons and deactivated all of that planet's robots. Jeff and Norby attempt to thwart the invaders who, they discover, believe that technology is bad. They all learn that only misuse of technology is bad. This book and "Norby and the Lost Princess" (the third book in the series) were also published together as "Norby: Robot for Hire."
