This was a case of 'it's me'. I can definitely see why people like this book a lot, but it just wasn't really for me. It somehow slipped my mind that I don't really enjoy superhero stories (whether in book or movie form), and even though this is both a villain and hero story at the same time, the whole EO concept wasn't that fascinating to me. 
 For me, it was an OK read, it took some effort to get through, considering that it is not that long of a book. I didn't really click with the writing style of Schwab, and though I felt like the characters had a lot of potential I just somehow didn't really care for them. It's hard to explain why I'm not loving this book, but I just wasn't... 
 I think I will try one of Schwab's YA books in the future, considering that those are more fantasy. The Monsters of Verity duology sounds more interesting to me.
