** spoiler alert ** 
 I am not sure how I felt about this book. I am making my way through the books on NPR's best YA novels and I am not sure how much this stands out. It will stick with me probably but it seemed pretty cliche. Popular girl realized she isn't like the rest and has to do things differently to be a better person etc. The death twist was interesting but I was REALLY disappointed that in the end we weren't told which of those days was the one people remembered. It also felt like Sam did a lot of things because she had to to escape the purgatory state. I didn't hate it but I didn't love it either. I will still keep it as an option for my students to read though :)
