I really like this book! It is so darn captivating. I adore the concept from the beginning it gives off the impression that you are the main character, and you are in the story which i love because then it seems more personal to me in my opinion. I was really interested in this book from the cover and the blurb. It did take me a while to get into it and I nearly lost interest but then it started to get really good and I got more invested. In terms of characters, Ada is a very interesting character in that she's so obsessed with getting in with the 'right' people that she is missing out on living her own life but you can see how she gets dazzled by it all. She wants to feel something that she is most definitely not. The book is so cleverly written, I had guessed a part of the solution fairly early on but that was in no way the whole solution. A wonderfully dark and chilling read. you must certainly have a read!
