When Sienna, a limelight-stealing older sister, and her frustrated brother, Kiel, witness four unidentified flying objects, they and their three friends find themselves walking through a swirling mass of illuminated energy, being pulled towards galaxies unknown and enemies bent on vast destruction. The five kids are offered the chance to realign the energy cords that protect the Earth and connect it with their newly discovered planet, Tronkeelin, and they jump at it. The fate of both planets is in their hands. But before they can accomplish this monumental task, the kids must first find the missing Tetene Element, navigate a complicated wormhole network, escape disintegration, withstand immense radiant blasts coming from the four corners of the universe, and outwit the vicious Eegreds and Saters who want nothing more than to pillage and destroy both planets. But the clock is ticking. Sienna, Kiel, and their friends must find some strategies to accomplish everything before the Earth and Tronkeelin are forced to give up all of their resources and treasures.
