I am pretty happy with the end of my book. It was a pretty normal ending. The team kills the bad guy and Jake and Ben work together to save the world. But normal is getting boring. If I could change the ending of my book, i would make allow the bad guy to win and people start dying. That would be a unnormal ending and a surprise to the reader. I get very bored with normal endings, so if I could make it the ending sad and then set up a sequel, its a win win. I think more authors should change the ending of their books because they are starting to get unoriginal.
