So I want to write a book that's set in a very different and otherworldly world, so I thought about it and I was wondering if it was ok to put a lot of things into context. However, I think I went a little bit too far considering that the prologue is more than half the length of the entire novel. Is this ok?
I am thinking it's fine, because the world is soo different, but is there a golden rule for determining the length of a prologue, and not whether I should write one obviously? How long should it be?
