question:
A total waste of paper...even my Kindle can't fix that. It's no longer about the story, it's all just sex with people other than the characters you've spent so much time developing. Don't bother buying it! Seriously disappointed!!! If you liked this book, or have read some others, then don't bother, not worth wasting your time.
answer:

Bad review
