After struggling to finish this book, all I can say is: I am disappointed. 
 I really wanted to love this. I felt the characters were interesting and the plot had potential. But I found myself struggling to finish this out of pure boredom. 
 A few issues I had with this book: 
 - The character of Barrington Whelk. I hated his backstory, felt he was an unnecessary addition to the story, and honestly wish he had never been included. 
 - Gansey's bipolarness. Gansey was possibly the most frustrating character I've ever loved to hate. At times I really loved him, and at other times I felt like he was the ultimate hipster/emo persona. If you were to ask me who he really truly is as a person I wouldn't be able to tell you. There's being interesting and multi-faceted, and then there's being a completely different person depending on what scene you're in. 
 - Blue's father. Towards the end of the book Blue's mother shares a theory she has for his disappearance, but it's never explored. Here is a woman who spent the entire first half of the book being secretive about asking her friend to find Blue's dad and when she finally tells Blue all about it, nothing comes of it. Really? 
 - Noah's big reveal and the boys' reactions. I just couldn't believe how no one was sufficiently freaked out about this. 
 - Ronan's issues. In the beginning of the book it's clear that Ronan has issues. With his dad's murder, his schooling, and especially his brother. During the middle of the book Ronan's brother disappears and we never hear about him again. There's no resolution to their issues as a family or even with Ronan's grief. He just adopts a baby raven and calls it a day. I was really disappointed with this. 
 - Blue's deathly kiss. WHY BRING THIS UP WHEN NOTHING HAPPENS?! You're such a tease, Stiefvater. 
 - The ending. The end was frustrating, lackluster, and disappointing overall. When there finally is some sort of resolution, it's glossed over or passed on to someone else to fix or deal with (Whelk, Neeve, Adam, etc.). Adam is one of my favorite characters, and in the end all we know is he went through some inherent change and moved out on his own. So I'm guessing he's happy, but I don't really know for sure. It's beyond frustrating. I NEED SOME CLOSURE, STIEFVATER. 
 However, not everything was awful. There were some positives I noticed: 
 - Different characters narrating the chapters. I like when Stiefvater does this, I feel like she has a way of varying the narrating so that you know it's someone different talking. 
 - The three psychics. Calla and Persephone were my favorite characters in this book, hands down. They added some humor to the story and had a lovely dynamic between them, I loved them. 
 - Blue wasn't an idiot. At least, I didn't feel she was, and that's such a rare thing in books like this so kudos to Stiefvater for not writing a character that I immediately wanted to choke to death. 
 Unfortunately the cons outweigh the pros by a wide margin in this case, so I had to give this three stars, but I'm sad, because a lot of people loved this and I really wanted to as well. It just didn't work for me in the end.
