A well written book is so much easier to read that I'll pay the premium (within reason). When I read a textbook by Hadley Wickham, I can tell how much he loves novels; he knows how to write in a way that's engaging for the reader. I've tried to slog through technical books that don't have the same writing level (despite the same technical proficiency of the author) and it's painful.
