But then I geared up to writing my 11th book, and something strange happened. I knew the ending first.
I fought it. I tried to push it aside, but the final scene was too powerful for me to ignore. This forced me to get out of my comfort zone. I eventually started writing with the ending crystal clear in my mind.
I won't lie. This freaked me out.
UPDATE: In the end, even with some ideas on how my book would end, it turned out there were still a few surprises. I guess it's great to have some ideas about how the ending will look, but again, if you're surprised by the final pages of your book, so will the reader.
