While I thoroughly enjoyed this book, I was quite disappointed at some point that it didn't lived up to my expectations on how the series would end. I truly believed that this last book has gone through a lot of process/editing to stay true to the plot and how the first book was established. What I really liked about this last installment is that I felt that the characters evolved as the story progresses. Although disappointed for the lacking of romance in the series, I guess it's not the main goal of the book but I still appreciate how the author managed to put it in there as the bigger picture, for me it just lacked emphasis and emotion. 
 Overall I think the series is a must read. The story Arin and Kestrel is definitely one to read and recommend.
