I couldn't finish this - only my second DNF of the year. I struggled through about 120 pages before getting too fed up with it, then skipped to the last 50 or so & didn't feel like I'd missed anything. Unlikeable MC who insisted on p3 she was different from everyone else - and kept doing it sporadically for the rest of what I read. None of the other characters were particularly likeable, either. I'm not actually sure who's side we were supposed to be on, if any of them. There was a whole lot of obsession masquerading as love, which may have been the point but just wasn't interesting or appealing to read about, and people using and lying to each other pretty much the entire time. 
 If I'm summing up, I think it wanted to be this dark, eerie, witchy thing but to me it just felt as fake, self-obsessed and wannabe as the characters. Horrible. Cross Twilight with every bad goth-teen movie you've ever seen, only without as much sense. Oh, and it seems to be set in the UK but uses American spellings. Might be a personal thing, but that's always going to bug me. 
 If I'm feeling charitable, I guess it might have appealed more when I was younger? Although some of the content is such I don't think it's aimed at the younger end of YA particularly. Anyway, I've read young YA books that were so much better, so I don't think that's the root cause of my dislike.
