It is not seldom that writers misjudge their audience. Writers may declare that they write for boys and girls between ten and twelve, while the implied readers of the novels may have to be slightly older and more mature to understand the character, or the character’s experiences will only appeal to girls, or the particular settings and events of the novel presuppose a certain knowledge of the British public school system in the nineteenth century, or the intertextual links address reader with substantial reading habits. All this does not necessarily prevent real readers from enjoying a text that postulates a different implied reader.

– Maria Nikolajeva in The Rhetoric of Character In Children’s Literature

A lot of writers say that they don’t think about the reader at all. I’m a complete fucking whore for the reader. If someone picks up my book, they’re really doing me a fucking turn, and I want to give them a good time on many different levels. So I try to make every page and sentence pop. And that causes weird technical difficulties as a writer. It makes your work very intense as a reading experience.
