Acorna

A small girl is found alone in an escape pod, adrift among the asteroids. She has a tiny horn in the middle of her forehead, odd feet and silver hair. Her powers are unusual: she cleans foul air and water, coaxes plants to grow, and mends broken bones and scars.

Three grizzled prospectors pick her up and adopt her. They carry her to Kezdet, a bandit planet where nobody asks questions, hoping she can grow up there without anyone interfering with her life.

Kezdet hides a dark secret. Its wealth rests on a brutal trade in child slave labor, run by a man known only as The Piper. He has plans for Acorna and for her abilities.

Acorna does not share them. As she grows from a child into a young woman, her love of freedom grows with her, and she sets about pursuing aims of her own on a world built on the opposite principle.

This is science fiction, set among asteroid fields and on a lawless frontier world. It follows an unusual heroine from childhood into adulthood, with a found-family warmth around the prospectors and a darker current in the slave trade that Acorna comes to oppose.
