On Writing, by Stephen King
First, I want to say this: Don't feel cheated that I have not outlined Stephen King's theory about wriitng here on this site. The fact is, I'm doing you a favor.
One of the most important things to realize as a writer--and this comes straight from Stephen King himself--is that writers must read. For this reason, I have decided not to devulge any more information about King's theory. Rather, I hope that you take my word that it is a book well worth your time. Buy it. Rent it. Listen to the blasted thing on CD if you want.
You won't regret it.
