I love the idea of this book, and though I will admit to hating Sam for much of the first half, I found myself rooting for her in the end. I would have liked more resolution, I guess I'm selfish that way. But I really wanted more from the ending. The story is thought provoking and really makes you stop and think about how one small action or movement can change and shape so much in not just our own lives, but others as well.
