Man oh man did I LOVE this book. Everything from the plot to the characters to the motherfucking FRIENDSHIP to the illustrations and signs scattered throughout. I loved this. Normally contemporary isn't my thing, but the graffiti brought something else to it because I love all things illegal (in fiction). 
 Things definitely didn't play out like I thought they would. The parents weren't non-existent. The friendship was so natural. (view spoiler)[ I totally thought the book was going to be super cliche and have KS be the tagger and then Julia and the prick would fall and love but thankfully that didn't happen. (hide spoiler)] 
 I loved how there were gaps in the book's dialogue. It gave it more of an authentic feel. Pretty much I thought I wasn't really going to enjoy this, but I ended up loving it and laughing and smiling and crying and smiling some more. 
 I am very sorry, but I did a pretty shitty job of looking for TRIGGER WARNINGS in the book: eating disorder, ableism is called out, bullying, brief joke about alcoholism, cheating on significant other
