I was sad to see the series end, yet I was also happy there WAS an actual ending. I'm curious to see if there will be any spin-off books made in this world where Hsin/Boyd appear as cameo characters -- just to see what answer they chose to the question posed in the final chapter of this book. 
 The series as a whole was a pretty emotional ride - I did cry a few times; which, in my estimation, shows that this writing duo is pretty talented. 
 The only reason this series doesn't rate a higher star rating from me is that I definitely feel the story as a whole can use a major edit. There are a lot of times when I would just skim a lot of the repetitive character introspection.
