Teenagers across North America begin to vanish without a trace, pulled from their beds in the middle of the night.
They wake up in Zo: a virtual Earth that looks familiar but plays by its own rules. No adults. No way home.
Here, each of them is changed-stronger, faster, sharper-in ways tied to the one thing they all have in common: their zodiac sign. As alliances form and rivalries ignite, it becomes clear that someone is watching. Studying them. Waiting to see which sign-and which teenager-proves supreme.
But Zo is hiding a secret far more dangerous than any of them could imagine. And getting home might cost them everything.
Does your sign have what it takes to survive?
