"He was a book, and he was holding his final pages, and he wanted to get to the end to find out how it went, and he didn't want it to be over." 
 I wavered between four and five stars on this. There are a lot of mysteries here but after rereading certain passages, as well as going back in the series, I was able to connect enough dots to give it the five, because otherwise The Raven King managed to get me going and that isn't easy. I am a very relaxed reader. I don't cry easily. My heart doesn't often pound even during scenes that should be intense. But all those things happened during this book from the point of the bizarre "Raven Day" ceremony onward. Come the last quarter my sinuses would start to sting off and on as I could see what was coming. 
 The end, when it came, came a bit too quickly for me. I would have enjoyed more aftermath. I think the pain attached to one aspect could have been drawn out longer, especially after four books of build up. But ultimately the emotion and character interactions were all that I could have wanted them to be, even if wrapping it up so quickly seemed to drain the series of a small measure of gravitas. 
 It's really difficult for me to wax on about what I loved without specifics and I'm not going to go into spoilers. 
 Readers who are predominately passionate about these characters and their interconnections I think will be satisfied with the conclusion. Although I feel deep melancholy in regards to Noah but again can't really explore that here without detail. This is sadness appropriate to his story thread so it's not a complaint. The conclusion of Noah's story was the only case where I felt even more bitter-sweetness than I had expected. Due to how some of the other character's story lines worked out it, my almost lack of satisfaction in regards to Noah actually seemed to create a necessary emotional balance. 
 Those who want/need to really understand the how's of the mysteries (especially in regards to events connecting the ley line, Cabeswater, Gansey, and Noah) will have plenty of food for thought as I've gone over it all for a bit and while I managed to answer some of my own questions, others I am still hanging on. If you are one that needs clarity on all this you may find yourself frustrated. 
 If anyone other than me was longing for some great Blue-Ronan interactions (it was the less developed friendship in this group) there are more of those here, once when I really needed the humor to get a breather. 
 I loved Henry Cheng and ended up feeling sorry he wasn't a little more present leading up to TRK, but also can see that his place in the group fit better in the context of where they were heading in the future. Throughout the series it was clear that few of them had future plans that aligned and the question of what happens 'after school' or 'after Glendower' was handled in a way that allowed each one of be true to themselves while keeping the sense of friendship and even hints of future adventures. 
 I really want to know how the camaro ends up losing it's tires ...
