Constantin Film has secured the rights to Neal Shusterman's bestselling novel Unwind, Variety reports. The sci-fi adventure, published in 2007, is officially described as follows:

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.

Marc Benardout, Catherine Kimmel, Robert Kulzer, Julian Stone and Charlotte Stoudt are attached to produce with Martin Moszkowicz executive producing.
