The Doree Chronicles

Conrad, 22, has signed on to write a three-book series of young adult fiction for HarperCollins, the publisher tells PEOPLE. The books – the first of which is scheduled to hit shelves in the summer of 2009 – will be loosely inspired by Conrad’s own experience going from an ordinary teen to a reality TV star.

“It’s definitely influenced by my own life,” Conrad tells PEOPLE. “The books are about a girl who moves to L.A. and stars in a reality show, so obviously there are some similarities.”
