I bought this book at the beginning of college because I saw recommendations for it on Tumblr. I didn't start reading it until the end of last summer (I was 22 at the time), and I just not finished it (now 23) after taking a very long hiatus. 
 I had a hard time getting into it at first. Things seemed a little repetitive, and it took a while to get to the meat of the story, which is when Sam, the main character, dies. Being that each chapter is 80 pages long, it's hard to be waiting that long to get to the meat, which didn't happen until the end of chapter 1. 
 With that said, once Sam died, I really enjoyed reading about her experience in the afterlife - her reliving the last day of her life, February 12, for seven days. Her thought process, though I can't relate to it as much now, definitely reminded of my mindset when I was in high school. In this aspect, the book was well done. Each day Sam is trying to unravel the mystery as to why she can't move on in death, why she is forced to relive her last day. And each time she relives it, she has a new approach. 
 I was under the impression that on the seventh day, when it was all said and done, there would be a huge lesson not just for Sam but for us as readers. And all the questions I had throughout the book, I was expecting and ready for answers - a big aha moment. That didn't happen for me, which is why I'm only rating the book as an average three stars. 
 I enjoyed the build up. Once I got over the hump at the beginning, I found myself wanting to know what happened next. Each time that Sam relived her last day, I was eager to see what lesson she would learn and what information we'd be given that would ultimately help Sam to move on in her death. But the end of the book was so anticlimactic. There was so much build up and suspense, and it ended with a handful of big questions unanswered. And on top of my big questions being left to the imagination, the ending was so abrupt, too. The final chapter ends with Sam officially dying for good; that's fine, and I'm okay with that. But I was hoping the epilogue would give some insight into what happened after that. What happened to Juliet? Did Lindsey ever change? Did Lindsey and Juliet ever hash out their differences? What about Kent? I was convinced that Kent might know that Sam was dead and reliving her last day; I thought maybe he was in the same situation, and I was halfway expecting them to work together to move on in death. I got no closure on this. And I had a handful of other questions as well. Nothing was never answered, so the book ended with me feeling very unsatisfied. 
 I just wanted more from this ending. The concept and plot are very interesting, and I wish there had been more closure to the whole thing.
