In the year 2000, a mysterious invasion took place on Earth. Billions of humans vanished, until the amount of them could be counted with only one pair of hands. Now 18 unanswered years has passed and the few who were left on earth were saved and taken to a faraway planet called Helios. People there call these humans The Outsiders. No one knows what happened to them. Some say they are killed, but some also believe they live among the civilians in Helios. • Jae and Sawyer, two young students from the Academy of Eos, together with the beloved Holden Price, sneak into the secret project of the mysterious senior-student Rue Lennox only to be found on a spaceship headed towards earth.
