I don't know where people got the idea that characters in books a supposed to be likable. Books are not in the business of creating merely likeable characters with whom you can have some simple identification with. Books are in the business of crating great stories that make you're brain go ahhbdgbdmerhbergurhbudgerbudbaaarr.
The characters within a book were, from a certain point of view, identical on some fundamental level? There weren't any images of them, no physical tangibility whatsoever. They were pictures in the reader's head, constructs of imagination and ideas, given shape by the writer's work and skill and the reader's imagination. Parents, of a sort.
All morning I struggled with the sensation of stray wisps of one world seeping through the cracks of another. Do you know the feeling when you start reading a new book before the membrane of the last one has had time to close behind you? You leave the previous book with ideas and themes -- characters even -- caught in the fibers of your clothes, and when you open the new book, they are still with you.
