I'd finished the first two [books] and they were going to to be published, and [editor] said, "We need you to write a summary that will drive people to these books." And it took forever. I couldn't think of a thing to say. I looked at the back of other children's books that were full of giddy praise and corny rhetorical questions, you know, "Will she have a better time at summer camp than she thinks?" "How will she escape from the troll's dungeon?" All these terrible, terrible summaries of books, and I just couldn't.
