In this book we see seven diferent versions of the same day. Even if it might seem repetitive its not because the subtle changes and the big ones make the book very enjoyable. There are also many things that get explained along the reading, and something never happens twice the same way. Its really incredible how the author wrote this book and succeeded in making a very good story. At the beginning you wont like the main character at all, mainly because shes very mean with everyone except her reduced group of friends. But as the story progresses she realizes that life is short and is meant to be enjoyed. I likef the fact that it's not the typical YA novel where everyone and everything ends happily ever after. Its a lovely and depp story and it makes you think about a lot of things.
