Character development is what I value most as a reader of fiction. If an author can manage to create the sort of characters who feel fully real, who I find myself worrying about while I'm walking through the grocery store aisles a week later, that to me is as close to perfection as it gets.
'Twilight' passed like a fever through the sophisticated reader and the unsophisticated reader alike. People devoured those books in single sittings, over weekends, with a kind of raw intensity that is rare.
When you are on assignment, you stick to the facts, limit your vision, and often cut out the most revealing material. There is no texture, no shades of gray. In fiction, you can bring the reader on the perilous journey with your characters as they discover that war is more like a wilderness of mirrors, full of danger and uncertainty.
Two of my three siblings are older, so I suppose I learned from them and became a very avid reader at a young age, which I think enough cannot be said for what you can discover through literature.
I would be a liar, a hypocrite, or a fool - and I'm not any of those - to say that I don't write for the reader. I do. But for the reader who hears, who really will work at it, going behind what I seem to say. So I write for myself and that reader who will pay the dues.
I'm a professional non-fiction reader, that's what I do. But in my 20s we had our own vampire and witch moment, courtesy of Anne Rice, whose books I read and loved.
Your protagonist is your reader's portal into the story. The more observant he or she can be, the more vivid will be the world you're creating. They don't have to be super-educated, they just have to be mentally active. Keep them looking, thinking, wondering, remembering.
Sometimes a book is better than it ever had a right to be because of the history the reader brings to the reading and because of the methods educators use to bring a particular story alive.
Gentle reader, the Fountain of Youth is radioactive, and those who imbibe its poisonous heavy waters will suffer the hideous fate of decaying metal. Yet almost without exception, the wretched idiot inhabitants of our benighted planet would gulp down this radioactive excrement if it were offered.
I'm a big reader. My kids love reading, and I think it's important, not just for development but for bonding. You start reading to kids before they can even understand what you're saying to them, so I look at it as a fundamental tool for connection.
