Some authors do it. Some do it regularly. But for the life of me I don’t get how someone can craft a 1,000-page novel.
The longest book I ever read was Stephen King’s It. Now, there was a ton going on in that book so, it makes sense. I find getting to 300 pages, which is roughly 90,000 words to be a chore. So, kudos to those craftsmen and women who can do it, and do it well!
