Worlds populated solely by teenagers seems to be the rage in Hollywood this weekend as we head into the Holiday. First came news of the zombie thriller 19, which finds the world's populace turning into the walking dead on their 19th birthday, then DreamWorks announced they were picking up the YA novel series The Fire Sermon, which finds twin teens jump starting a repressed society, and now comes news that Warner Bros. has picked up The Young World from writer Chris Weitz.

The synopsis for this post-apocalyptic YA novel trilogy also finds teenagers dealing with a devastated earth:

"Teenage survivors inherit a destroyed and desolate earth, after a cataclysmic event kills off every person not between the ages of 12 and 21. Ill-equipped to restore society to working order, the surviving residents of New York City must try to rebuild their world from the ground up."

Chris Weitz will produce and direct this adaptation of his own work, with the first novel in stores later this year from publisher Little Brown.

The writer is no stranger to YA fantasy fiction and teenage melodrama. He also directed the failed 2007 franchise non-starter The Golden Compass, as well as 2009's The Twilight Saga: New Moon. He made his directorial debut with the popular 1999 comedy American Pie, which evolved into a huge franchise for Universal.

The Young World is the director's first attempt at penning a YA novel series.
