Trapped on the ice planet of Delon, gamer girl Sofi and Ambassador Miguel have discovered that nothing is what it seems, including their friends. On a quest to rescue Shilo-Sofi's brother that everyone else believes to be dead-Sofi and Miguel must now escape so that they can warn Earth about Delon's designs on humanity. But the more they discover about the planet and Sofi's past, the more they feel themselves unraveling, as each new revelation has Sofi questioning the very existence of reality. Meanwhile, back on Earth, Sofi's mom is battling a different kind of unraveling-a political one-which could cost lives, positions, and a barely rebuilt society if the deal made with the Delonese is discovered. But there's a secret deeper than that-one locked inside Sofi that's ticking away with the beginnings, endings, and answers to everything, including how to save humanity.
