Valhai (The Ammonite Galaxy Series, Book 1)

At four, Six had been thrown out to fend for himself in the uninhabitable zone. Ten years later he is doped and shipped off to another planet as an apprentice. He is inclined to think that things couldn't get much worse, but that was before he was thrown into a cell with Diva.

On Valhai, The Sellites live their lives shut inside skyrises. So it's a big deal for Grace to pluck up the courage to defy regulations and venture outside onto the planet - a small first step that will lead to giant changes in her life.

She is the only person who can save the donor apprentices - but if she does it will ruin her family, and change her planet forever.
