The plot is fantastic in this sequel. FANTASTIC. First, I want to say that I love the concept of this book. A LOT. It really is genius. I don't even understand how someone can come up with this stuff! I'm in complete shock. And because of that, I don't think I will write a summary for this book just because I don't want to ruin it. The book completely veers in a new direction from the first book. Pretty much from page 1 Stiefvater will blow you away. I'm not kidding. 
 HOWEVER, even though there are new revelations all the time, this book was a slow burn for me. It didn't feel as fast paced for me as The Raven Boys did but a lot of little stuff builds up for a big finish at the end. And even though it was slow at times, it's totally worth it. 
 Also, on that note, I have to say, I'm not the biggest fan of Stiefvater's writing. I'm not saying it's bad. In fact, I actually think it's good, almost literary. The language is great and I can see how she's improved from her previous books. The problem is I like fast paced novels to have matching fast paced writing and her writing is very descriptive, detailed, and deliberately slow. It's hard because I want to figure out what's happening and she's busy explaining the precise color blue of the sky. It's frustrating for me. The writing is probably why I found the beginning of this book to be slow. 
 I told you how the book went a completely different direction from The Raven Boys, right? Well, I think that is my main critique for this book. Not that I didn't like the book but I missed the Glendower search. Nothing really progressed for the search throughout the book and it made me sad. 
 Once again, I'm really in love with all of the characters in this series. Also, we have a new character in this novel...a villain, if you will. His name is the Gray Man or Mr. Gray. He is quite the perplexing character and I still haven't figured him out yet. I think there is more to him than meets the eye. But so far I really like him. I WANT MORE MR. GRAY!!! 
 This book seemed to focus a lot on Ronan, which was great because Ronan is so cool! I would say I love Ronan but he's not really a "lovable" character....so yeah. I'm not even sure if I could imagine him in real life, but the way he is talked about in the book makes him more alive than almost all the other characters in this story. 
 Also, there are some developments with Adam's sacrifice at the end of The Raven Boys which actually made me not like him as much. AND of course, there's the moment when Blue starts debating whether she actually likes Gansey.
