I’ve read that, when you get to Act III of writing your novel, you are not supposed to add any new information. But I’ve also read that it’s ok to break the rules of writing if it’s done well. So, do you add new information after Act III or not? I say, if it works use it. Then again, before you use it, run it by some beta readers (those who critique your work before you publish it) and get their feedback first. After all, you don’t want to push your reader fans away by disappointing them.
