NEW YORK - James Frey is writing for young people and Hollywood has signed on.

Frey, a former screenwriter best known for his discredited memoir `A Million Little Pieces,' is collaborating on a four-book series of teen science fiction novels that HarperCollins will publish.

Screen rights for the first novel, `I Am Number Four,' have been acquired by DreamWorks and `Transformers' director Michael Bay.

Frey's co-author is Jobie Hughes, a recent graduate from the creative writing program at Columbia University.
