This cover grabbed me right away, then I saw it was Jessica Goodman and knew it would be un-put-down-able! As is often the case with YA who is evil and who is safe is indistinguishable as they are all going through their own challenges. I love the sister storyline in this book. Sibling conflicts so often seem so personal, but really siblings just have their own "stuff" they are trying to deal with. I cannot wait to devour every page of this one!
