Hannah isn't like most girls. For one, she lives on a farm, a self-sustaining commune called the Collective. For another, instead of going to school, she has meditations sessions in a barn that end with the "scions" guessing the ten things on the mind of a man named Maxwell. Her best friend is a boy named Cody. They have a special relationship that has led Maxwell and the others the refer to them as "soultwins," despite how it irks Hannah. They seem to be the only ones who question Maxwell's motivations, and spend most of their free time daydreaming about the day when they will be old enough to run away. But perhaps they shouldn't wait that long.
