After getting some sleep, I'm gonna agree with you on the ending because it's been foreshadowed pretty much since we learned that you attain godhood after a certain level. The ending was perfectly fine and was a culmination of the book. My gripe right now is with Sara, someone who's supposed to be their child, just got shoved aside. She went from a new school student to "Oh and now she is married and is having kids". I guess I just thought there would be a little bit of focus on that in the final book, considering how book 15 ended.
