** spoiler alert ** 
 I feel like I have to say right off the bat that this book felt like a filler. I liked it a lot but it felt very much like filler, there were a lot of things that needed to happen since the next book is the last one so I get it but if just doesn't have the same character development that the other books did. 
 Audiobook note: Will Patton is a great reader and I'm glad that he's done all the books. 
 This book picks up where Dream Thieves left off, Maura is still missing, school is about to start and the quest for Glendower is plugging along. I really enjoyed that we continued to see Adam come into his place as Cabeswater's eyes and hand as well as his place in the group and understanding how Gansey really feels about him. We finally meet Mallory in this book, and he's exactly what I expected from the other books. There isn't much growth of this character in this book and aside from the news of his discovery he probably could have been left to a phone conversation he certainly didn't need to travel over. 
 I liked how we continued to see Ronan develop in this book especially at the end with Blue. I'm nervous about the Mathew revelation and how Stiefvater is going to wrap that issue up. 
 This book had 2 sad moments of loss that I felt were a bit glossed over which was frustrating, I just feel like the moments needed some space to breath, and while one was in an action scene the other had the space and time to breath but Stiefvater didn't give it what it needed. 
 Oh also Artemis, what the what. I'm curious to see how that plays out because obviously Maura is going to pick Mr. Grey but he's such an odd duck. Very curious indeed. 
 As for the Epilogue: holy majoly. I knew Neeve was going to come back up at some point but I didn't expect it then or that ending at all and am very curious about what that is all going to end up meaning and the issue of the wrong number of people opening the door, or the fact that it's not human. So many questions raised in the epilogue
