This is how you wrap up a trilogy! 
 What do I even say? One of the things I liked best about this series, but especially this book, is how grey and shifting good and evil are. Those that seem evil had good intentions and those who meant well often ended up doing things that looked bad. There were no easy answers and I never felt manipulated into hating certain characters while supporting others. On both sides of the battle, I felt everyone was doing what they thought best with the information they had at the time. 
 The ending was explosive and exciting! No punches were pulled -you know its not YA when a lot of good people are *gasp* actually dead come the end. Sanderson didn't create more mysteries than he could explain; everything tied together and was revealed in perfect timing. 
 I really struggled with the middle book of this trilogy but am glad I pushed on.
