I meant to review this book a long time ago but I forgot. 
 The good stuff : 
 - The writing was pretty 
 - This is not a sappy, stupid teenage romance or whatever is marketing these days. There is only a light romance atmosphere sprinkling throughout the book, which is quite enjoyable 
 - The character are alright, not stereotypical, and interesting at moment. 
 - A little plot twist that I did not predict before hand. 
 - And the first chapter is absolutely cool and magical, really pull me in the stories 
 Now onto the bad stuff, which is why I rate this novel two stars : 
 - BORING. So BORING I can't remember what the plot about. You know some novel, like Gone Girl or And Then There Were None, can create such a great mystery that drawn you deep into the novel. Not The Raven King. This book is so boring. 
 - Plot moves as a turtle pace. Not much explanation about the magic system. 
 - I don't care that much about the ley line - there isn't seem to be anything urgent or crucial that make me dearly wish the character to find them 
 - The villain is dreadfully boring 
 - Characters are not super well-drawn, though I love gansey :D, but again, they are dreadfully boring, nothing beyond your typical abuse kid/bad boy/leader. Eh. 
 - Lack of Theme - my biggest pet peeve in most novels. I read books to change my perspective on the world. That's why, some books, though seemingly pure entertainment - such as Agatha's murder mysteries, still entertain me because it contain little philosophical messages about death, love, jealousy...etc. YA novels just make me snooze because I don't understand why I supposed to care for these teenagers beyond their supernatural quest or angsty problems. They are just like caricatures exist on the page, 1-Dimensional hero that seemingly impossible in real life. 
 - Now if there is no thematic message to be conveyed, then I desire a quick moving plot, humor, or creepiness. This book offer me nothing, beside some pretty description, some handsome boys from a rich prep school, and some boring, supernatural thing, that though original, doesn't give me any emotion. 
 So two stars :) But again, I am a very harsh, snobby critic - that type of critic who read Mill political treatise for enjoyment and burn Twilight in a bonfire. So don't take my word for it. Other YA bloggers are better authority in judging these novels. But also in my honest opinion, compared to a lot of other teen novels, I think this book is very original, great, and not at all stereotypical or annoying. Its biggest flaw is just that it's so BORING.
