Chris Weitz to Write Young-Adult Novels The writer and director Chris Weitz is trying his hand at young-adult fiction. Mr. Weitz, who directed "The Twilight Saga: New Moon," will write a trilogy of post-apocalyptic novels for Little, Brown Books for Young Readers, a division of the Hachette Book Group, his publisher announced. The first book in the series, "The Young World," is expected to be released in spring 2014. Chris Weitz offers a premise that is completely provocative and irresistible for teens: What if we ran the world? Megan Tingley, the publisher of the division, said in a statement. We were impressed by his ability to tell a timely and compelling story that is every bit as vivid on the page as it would be on the screen.
