I already explained my weird introduction to this series in the previous review I've wrote 10 minutes ago, so I won't repeat myself but it still stands and impacts on how I enjoyed this book. 
 I loved this one a lot, it was fun, fast-paced and action-packed. The characters start to grow out of the sadness and anger (namely Ronan and Adam, whereas Blue and Gansey finally come together) and their relationship, the friendship between the 4 of them, is at its best. I loved all of them here. I even loved cartoon-ish villainess Piper, not going to lie. 
 I read the last 3 books one after the other (literally finishing one and starting the next one in the next few seconds) so I get #3 and #4 a bit confused, to be honest. 
 In this book I got to love Ronan even more, but I became a bit disappointed on the fact that since book #1 (as I seem to remember), Blue has been losing protagonism, and that some major events we didn't get to see from her POV. I would've liked that.
