Noah discovers the secret to making E-Delta fertile, but first he must stop the Thunderstone Ring from crushing Earth. The strain of executing the strike on Earth has made E-Delta unstable and the kids are evacuated from the Bioplex in the hope that salvation will arrive before the red giant rises. Noah must bring the thunderstone ring through space-time in a crazy attempt to save two worlds and right past mistakes.
Arushka is held captive on the planet E-Delta, where the Bioplex structure is the only thing that stands between the inhabitants and their hostile environment. You can't last long outside without an oxygen pack and during the time of the red giant sun, you can't last at all. Drako, the handsome leader of the E-Delta kids, advises Arushka to get used to her new home — she's sixty million light years from Earth and any hope of rescue. Noah and the Nomads have other ideas as Chip impulsively jumps through Noah's experimental wormhole. Noah pursues him and the two emerge on E-Delta and make their way inside the settlement after rescuing one of the young colonists.
