This review is going to be hard to write, simply because I loved this book so much. And I just finished it, so my thoughts are pretty jumbled at this point. The only coherent thing running through my head is "oh my gosh this was so amazing how can I write a review." 
 I'm going to give it a shot. 
 I am in love with so many parts of this book. I guess I'll break it down, in hopes of giving this review some semblance of structure. 
 1) The Writing 
 Maggie Stiefvater has an amazing writing style. It's not necessarily whimsical, but it's something close. She doesn't write like how some other YA authors write, with styles blending together. Her voice is distinctly her own. She uses a bunch of different writing devices, but two stand out as my favorites. The first is her use of metaphors. She doesn't just use them in the traditional sense, comparing one concrete thing compared to another concrete thing, ie the lake was like glass, as in the lake is clear, calm, reflective. She uses them to describe intangible emotions, things hard to measure and describe. Adam thinking that Ronan looks like a heart attack comes to mind. The second thing that I love about her writing is her use of repetition. Depending on where you began the story, it was about [...], they said his name like [...], Gansey felt timeless. The phrases are used enough that they're recognizable, but sparingly enough that they don't become redundant. And it adds another level to her writing, makes it almost magical. 
 2) The Characters (and their relationships) 
 Yes, I have mentioned this in my reviews for all of the books in "The Raven Cycle." But the point remains: Stiefvater knows how to write characters and relationships. This is honestly what made me fall in love with "The Raven Cycle." Theoretically, I would have enjoyed this series just fine if the characters had been different or not as well written. The underlying plot is interesting enough that I probably would have still read this. But then again, so much of "The Raven Cycle" is these characters, so without them I'm not sure what would have been left. And I liked the addition of Henry Cheng as well. 
 3) The Finale 
 By this, I mean the entire last book. Because, let's be real, we've all read a series that we loved with all of our hearts that went through a lot of build up only to utterly disappoint in the last book. Luckily, The Raven King is not one of those books! This wrapped up in a way that both satisfied the story and reassured me of the characters' immediate futures. There were some things that I had a feeling about (view spoiler)[Gansey wouldn't die permanently (since his getting stung is commonly referred to as his "death") (hide spoiler)] and some things that took me by surprise and yet made perfect sense. Stiefvater is not one for gratuitous twists. All of the events in The Raven King make such sense and fit so perfectly that you wonder how you didn't realize this sooner. And yet at the same time, it's not very predictable. I don't know how to describe it; the point is, Stiefvater struck a very nice balance. (view spoiler)[Also, I'm very happy that Stiefvater left things slightly open-ended so that she can continue the series if she likes. How did Glendower die? A few other questions I forgot? What's the new Cabeswater that Ronan is going to dream up? (hide spoiler)] 
 If this review still seems incoherent (which I'm sure it does) I'm sorry. I tried my best, but in the end I simply love this series too much to be able to accurately describe it. I am beyond happy with how it ended, and this is the first time in a while that I can say that.
