All in all, I thoroughly enjoyed this series. I grew very attached to the characters, both "good" and "bad." The more I learned about the characters, the more hazy and gray that distinction became.
I was a bit disappointed at how much ... shorter this book was in comparison to the first and second. I wanted more out of it. The second half of the first book and a good portion of the second book is packed with adventure and mystery and character / world building - enticing and enchanting. This book lacked those things; the whole story was focused on "the end." Ultimately, it did fulfill its purpose of explaining and concluding things. But it felt like that's all there was to this book; there wasn't a whole lot of meat. I would have been much happier if this entire book comprised the ending 50-75% of "Book Three". But instead, the storyline immediately began it's march towards conclusion. I'm probably exaggerating this to a degree; but that was my lasting impression.
I did not see the ending coming, so I found myself a bit heart broken.
Still highly recommend this book and this series to all!
