But I've always been fascinated with that prettiest-girl-in-the-class person that I never was, getting inside her head and showing that she's just as tormented and messed up as everybody else.

'Gossip Girl' came out in rapid succession over two years, so the endings always had to be suspenseful so that you couldn't wait for the next one.

My biggest fear in writing 'Gossip Girl' was that the characters would sound like stereotypical rich, air-headed heiresses. These were my friends. They were smart and multifaceted. They had interests and passions. They wanted to become lawyers and doctors and writers and filmmakers.

Back in my days as a children's book editor, my superiors caught on to the fact that teenagers were using the Internet to gossip about each other, and thought it might be nifty to develop a series of books about an anonymous high-school blogger who gossips about her classmates. The concept was passed on to me.

I avoid the young adult section altogether if possible, although it's sometimes fun to catch a girl lying on the floor, reading 'Gossip Girl.'
