Sixteen-year-old Tawny Tamblyn lives in the cyberworld of the future. She attends online school, and goes to parties as a sim character far prettier than herself. One night, her mother announces she is sick. But no one gets sick anymore, not since the Evolutionary Committee began sterilizing those with genetic imperfections- imperfects. When her mother dies, Tawny’s father announces they’re leaving, in the middle of the night. Soon, they are deep in the Lost Woods, where they sleep on the ground and forage for food. After getting separated from her family Tawny is taken in by a group of “wild people.” Micah, a boy Tawny’s age teaches her how to live in the forest. Danger lurks everywhere. City “protectors” are being sent to patrol the area, looking for runaways. When the protectors close in on their group, Tawny learns the horrible truth about why they are there.
