I don't really know what to say about this. Maddy was such a brat, and even though she died in the beginning of the book, the more Ella pretended to be her the more I hated her. If Maddy had any redeeming qualities, I failed to find them. She didn't deserve to have a sister like Ella. I think the lie got way out of hand, and she should have come clean a lot sooner than she did, but despite that I really enjoyed this whole thing. It was an interesting premise even if I did find a lot of things to be unrealistic about it.
