Well... don't hate me. Everyone loved this book but I'm not entirely satisfied with the ending of the series. I feel that I'm betraying the series giving it only 3 stars, but I slept on it and decided that it represents what I honestly feel. 
 THE GOOD 
 The first thing is the writing style; it's different, fresh and has a touch of magic realism that makes it beautiful and smooth flowing. The last three books had this style, but I found The Raven King to be the one in which it is more noticeable. I loved it, it made the pace smooth, fast and interesting. 
 In this book, the boundaries between what's real and what's a dream blur and you just don't know what is happening. The thing is, it is not exactly a dream... it is a nightmare! LITERALLY! Some chapters are creepy as hell and they are extremely well written. Even though I read the book during the day, my hands sweated, I had shivers and my heart beat really fast. If Maggie decides to write a horror novel in the future I'm definetely in. 
 My heart also beat pretty fast in some of the romantic scenes. The two main relationships continue to develop and my heart melted in some chapters. Pynch fans will be happy, I re-read some of their interactions a few times, I couldn't help myself :] And Blue and Gansey become even closer and cuter. Characters continue to develop and grow. 
 THE BAD 
 I think my main problem with this book is the ending. I was expecting Something more... 
 WARNING I'll try not to say anything spoilery, but if you want to be very very careful do not read this until you finish the book. 
 Here's the deal; the whole series goes very deep to the character's minds and we get to know them very closely, but after the series climax we don't hear their voices any more... it just ends. We don't read about what they all think after everything has ended as we did during the rest series with their insecurities, their dreams, their feelings and their mind. We are just told very briefly what they do in the short term. 
 There are a LOT of loose ends not only in the story but in the character's relationships. I could have overlooked them if they were only regarding the story... but I have come to care so much about the characters that I feel we were removed from their heads and hearts too suddenly. 
 In the case of Pynch, during the four books, we read about the start and the development of their relationship... but we are missing a resolution. (view spoiler)[ Is Adam really in love with Ronan or is he just experimenting? Are they a couple now? Or was it just a one night make out? What does Ronan feel about Adam leaving for college? Does Adam driving the BMW mean that they are closer? (hide spoiler)] 
 The same happens with the rest of the characters: how are they coping now that all has ended? How do they feel? (view spoiler)[ What the fuck was the deal with Gansey's refurbishment? (hide spoiler)] We had nothing... 
 The other thing that didn't work for me was Henry Cheng. I read that most reviewers liked him and think that he was a nice addition to the story. I felt he was an outsider the whole time and didn't belong as a main character, it felt forced. Maybe if he was just a companion I wouldn't have felt this way, but he was forced into being a close friend to Gansey and it didn't feel right. Even in the epilogue he felt like an intruder. Maybe he should have been introduced earlier... I don't know. 
 SUMMARY 
 It's good... but I was expecting Something more... 
 Also, I still can't keep myself from looking at Pynch fanart.
