Less than 15 months after signing his book deal, the filmmaker-turned-author has sold his debut novel. Warner Bros has picked up Twilight: New Moon helmer’s The Young World, which Little Brown will publish in 2014. Chris Weitz will helm the film and produce along with Andrew Miano. The young-adult novel is set in New York City following a catastrophe that kills everyone younger than 12 and older than 21 and leaves the survivors without heat, running water or the any of the amenities they’ve grown up with.
