Space Bugs, Earth Invasion completes the young adult fantasy trilogy that was begun by Pot of Gold and Enchanta. Space Bugs, Earth Invasion is written for children eight to thirteen years of age. In Space Bugs, David and Barbara Morgan from the Enchanta novel join up with their cousins Larry and Janet Garrison from the Pot of Gold fantasy story to combat the evil forces of wicked Queen Termita from planet Insectia. The Insectians are human-size insects that invade Earth with their superior technology. The four young teens go to Hammonds Grove, New Jersey's most famous landmark, Superstitious Rock where they wish for Rhymer the elfrechaun from the Pot of Gold story and Changer, Pretender and Inventor from Enchanta to assist them. The four magical beings appear and then help the Morgan and Garrison kids go to battle against Queen Termita's forces. The Insectians use weapons such as the Identatron, the Evilsizer and the Micro-Minimizer against the Earth's armies, but the children counter with the Trojan Spider, the Medusa Medallions and the Termita Touch. The kids even have to battle in a spaceship' arena Queen Termita's fiercest monster, the Insectaclops. Rhymer, Changer, Inventor and Pretender play many hilarious pranks that frustrate and eventually defeat the Insectian army. In the end, the Insectians sign a Peace Treaty drawn up by the children, and then they return to their home planet. Rhymer, Changer, Pretender and Inventor go back to their worlds, and everything on Earth returns to normal.
