The cliché I tried to avoid was I hated "teenage sidekicks." I always figured if I were a superhero, there's no way on God's earth that I'm gonna pal around with some teenager. So my publisher insisted I have a teenager in the series, because they always felt teenagers won't read the books unless there's a teenager in the story; which is nonsense.
