The Nemesis Comet is hurtling past the moon towards Earth. It is so close now it can be seen looming in the skies above the General Store, where the Nomads are refueling the Beast. The Nomads head straight for the Cortillo Plain installation. Sundance, an uneasy rookie driver, steers the Beast across country and through the installation's security fencing. Meanwhile, Myah and her brothers have commandeered a security vehicle and are sneaking past the installation's guards in a more subtle fashion. In the Operations room General Cardell ignores a young scientist's warnings about the disastrous effect his nuclear rockets will have on the Nemesis comet. The young scientist is Liz Frankiln, Noah's mother! This is an added problem for Noah and Arushka, who are hiding in the shadows. If they don't get the young Liz on a helicopter and back to the safety of the underground North Col research facility, Noah might not even be born! It's less then an hour till the rockets are launched and the Nomads are heading for the radio telescope. Arushka is on Moshi, riding alongside the Beast. Myah and the brothers, having failed to waylay Noah at the installation, are in hot pursuit in the security van. Arushka wheels them off course, causing their vehicle to overturn on the rocky desert plain. Noah aligns the Beast's projector with the radio telescope reflector. Myah, dishevelled from the crash, is determined to stop Noah from saving the Earth from the impact and wasting the precious Thunderstone Cube. Arushka wrestles her away from the Beast's controls, leaving Noah free to make the frantic last minute adjustments. As the rocket launch countdown nears zero, Noah hits go, sending the beam skywards. The Nemesis Comet is shattered and its blue rock dissipates harmlessly into space. While everyone else is staring at the spectacle in the sky, Myah and her brothers look down in horror. They are literally disappearing! And in Haven the Daniels and Monsoon watch the animals disappear and the landscape change. Now!… says Becky and dons the PH-Ts Noah left for her. The Daniels and Monsoon arrive at Cortillo Plain for a brief reunion with Noah and the Nomads before Noah makes a final command and they all white out together — side-stepping time to somewhere in the future.
