Chasing the Killer Comet begins with the introduction of a heroic 13-year-old girl named Jennifer Thompson, whose life is turned upside down when a mysterious new housekeeper enters her life, with outlandish predictions for Jenny's immediate future. The accidental discovery of a wondrous garment that has the ability to defy the laws of gravity, adds to the recent intrigue in Jenny's life. A traveler from another planet within our galaxy is the owner of the gravity displacement suit. The alien's planet has a shortage of water and they have visited Earth for thousands of years, collecting and transporting water back home. The story also involves the global discovery of an impending catastrophic disaster; a massive comet is hurtling through space on a collision course with Earth. Our planet is not capable or prepared to avert this disastrous event. Jenny realizes that Earth's only chance for survival lies with her and her link to the technologically superior alien being. With the housekeeper's guidance, they formulate a plan of action and make contact with the alien. Jenny uses the valuable suit as her main bargaining tool in her attempt to convince the alien to help her. She is terrified about the prospect of having to make contact with an alien, but it is Earth's only chance for survival, so Jenny courageously shoulders the responsibility. She makes contact and convinces the shy alien to look into the possibility of undertaking this dangerous mission. The alien likes Jenny and takes pity on her, and they devise a risky plan to move the mountain-sized mass of ice and rock away from its disastrous course. Join them on their exciting mission, as they race against time, and Chase the Killer Comet.
