Constantin Film has acquired the rights to Unwind, the 2007 best-selling sci-fi novel by Neal Shusterman. The story is set in a world where parents can choose to have their children "unwound," a process where their vital organs are removed and donated to others. Take a look at the official rundown from publisher Simon & Schuster.

"In a society where unwanted teens are salvaged for their body parts, three runaways fight the system that would "unwind" them

Connor's parents want to be rid of him because he's a troublemaker. Risa has no parents and is being unwound to cut orphanage costs. Lev's unwinding has been planned since his birth, as part of his family's strict religion. Brought together by chance, and kept together by desperation, these three unlikely companions make a harrowing cross-country journey, knowing their lives hang in the balance. If they can survive until their eighteenth birthday, they can't be harmed -- but when every piece of them, from their hands to their hearts, are wanted by a world gone mad, eighteen seems far, far away.

In Unwind, Boston Globe/Horn Book Award winner Neal Shusterman challenges readers' ideas about life -- not just where life begins, and where it ends, but what it truly means to be alive."

Constantin co-president Robert Kulzer will produce the adaptation with Marc Benardout, Catherine Kimmell, Julian Stone, and Charlotte Stoudt. No screenwriter or director has been attached yet.
