The Earth is in the grip of a new Ice Age, and when twelve-year-old Eleanor's scientist mother disappears in the Arctic, Eleanor sets off on a dangerous journey to find her--and uncovers a mystery, a crime, and evidence that Earth has been visited by extraterrestrials.
Desperately searching for the other Concentrators that are fatally disrupting Earth's orbit, Eleanor and her companions are labeled as terrorists by G.E.T. forces that would eliminate all but a few select people.
Eleanor and her mother Samantha are working seperately and preparing for a journey to find the Master Concentrator when an alien spacecraft lands on Earth and throws the globe into a crisis that Eleanor works to control.
