The Cosmotron is a repelatron driven spaceship that Tom is going to use to conduct a grand tour of all the planets in the solar system. However, Tom and his group must battle the group "Very Important Party of Extra-terrestrial Rulers" (VIPER), demonstrating that all of the creative energy for cool names was used up in naming the inventions. VIPER steals Tom's first Cosmotron so he is forced to build another in a very short time. After Tom and his crew go on the grand tour of the planets, the VIPER controlled craft attempts to battle Tom in his new Cosmotron, but they are easily defeated. Let by Tom and Bud swinging their fists to great effect, government agents storm the main VIPER hideout and free their captive.
There is slight shelf wear to the spine of the book. The pages are very lightly tanned but clean and the binding is tight.
