Loved this book! It might be my favorite in the series so far (but then again, it's been a few years since I read the first one so I could just be on a total QOS high). 
 (view spoiler)[ 
 I think whoever you ship Celaena/Aelin with will definitely influence how you feel about this book...for me, I was Team Dorian for the first book and did not get the appeal of Chaol at all. (COM is my least favorite of the series). And then HOF, I fell in love with Rowan and had hopes they would get together, but Maas seemed to keep indicating they were just friends! Well, imagine my surprise when they actually did get together in this book! I do wish there was a little bit more development for their romantic relationship though. 
 I absolutely adored Aedion in this book! Him and his humorous comments and just his great bond with Aelin were great. 
 I also loved the return of Arobynn and was shocked he got killed off! I twistedly loved his character and had hoped we'd see more of him...I guess I hoped he would eventurally redeem himself, but nope. 
 In HOF, I didn't enjoy Manon's POV too much because I just didn't understand who she was and exactly how she was going to fit into the story with the other characters. I liked her POV a tiny bit more this book since her storyline finally intertwined with the others. (But I won't lie, every time I saw the next chapter was a Manon chapter, I sighed.) 
 I saw some other reviewer's comments about how there should've been more POV from Dorian...and I LOVE Dorian but I mean, a monster was taking over his body. I don't see how there could be more chapters from his POV when it would've been describing the same thing? 
 Anyways, the ending of the book is awesome. I did love how Aelin, Chaol, and Dorian were together (Hooray! Original trio!). I also LOVED the Dorian/Chaol chat...their bromance is just the best. 
 It was a happy-ish ending with the group arriving in Terrasen, which was sweet. Although, how depressing that they left Dorian all alone at the castle! 
 All in all, I enjoyed the crazy action, drama, and romance of the book.
