I remember when I finished this book, I was sitting on my bed, hugging my knees to my chest, completely lost in thought; not really in shock but my mind was definitely working full speed. 
 I didn't feel heartbroken with this book, I knew what I was getting into, the summary says it all. There's also the fact that the subject is not uncommon, there are movies with this sort of theme, like the one with Sandra Bullock - Can't remember the name of the movie - What made this book so great and set it apart from other stories similar, was the characters and the situations Sam - Main Character - was into. She's what you'd call a Mean Girl, okay, I'll say it: A Bitch. She dies. But she also gets a second chance- actually more than two; as soon as she understands this she sets of to make everything in her life right. 
 A friend of mine was also reading the book along with me, but she found the process of Sam waking up again in the same day and stuff to be to tedious for her and barely managed to finish. I never found it tedious, I was anxious with every upcoming day to see what she would change, what truths where left to find and which ones was she willing to take to the grave. I was literary grasping the book as I read, it actually managed to survive just because it's a hardcover, still, you can notice I was on edge. 
 It does not have a Happy Ending, it's also not a Sad one, it's just an Ending. Lauren Oliver definitely did a great job and I have become one of her fans. You'll have no other choice but to Fall... for this book <3
