"There is not always a good guy. Nor is there always a bad one. Most people are somewhere in between." 
 I LOVE IT SO MUCH AND I AM NOW UNABLE TO WORD SO I WILL BE BACK LATER TO SHOUT ABOUT ALL THE FEELINGS 
 *forewarning* Please don't expect any sort of coherent review it ain't going to happen xD 
 And I am back. Things I loved: 
 - Conor's character growth and development 
 - The storytelling being sieved in perfectly with what was happening in the present say scene 
 - The Monster and his lessons 
 - The tone of the story and the beautiful writing for being both simple and have so much meaning 
 - The illustrations 
 If you've been recommended this book of just stumbled across it, read it. It's one of the books that is both simple and elegant that it trancededs age, it's illustrated but adult, the feelings and emotions are there, you know that this isn't going to be a fun happy story but the writing drags you down and taps you into the emotions making you angry, sad, mad, frustrated. 
 Also for anyone that mistakes the cover and thinks this is horror, it's a sad and scary story but not a horror in the usual sense of the word.
