Ryan and his friends Maya, Will, and Sofie are normal teenagers, struggling to get by in school and hanging out like good friends. But they've heard rumors. Rumors that tell of another planet capable of supporting life. Rumors that say humans haven't always lived on Magnus, but that they came from this other planet. This planet is called Earth. They have a mission: to get to the bottom of the rumors and find out what really happened in the past. One day in the library, however, the discovery of an old book gives them more than they bargained for. Ryan and his friends are landed in the middle of the Endless, the largest known desert, covering almost a third of Magnus. They set off on an epic adventure, unearthing many long-buried secrets along the way. With perils awaiting them at every turn, the four friends meet unexpected allies on their quest for the truth and a way out of the Endless. But a formidable foe from Ryan's past lurks in the shadows, awaiting the opportunity for revenge.
