I liked this books because it dealed with hard to talk about subjects like depression, death and teen pregnancy. The book was really well written and I loved the author's writing style. The ending was very incomplete. It wasn't a cliff hanger or anything-just unfinished. Cal was a very well developed character. He's very hard-headed. They both are. But at the end (the treatment) it was like he was just going with the flow and that made it very unbelievable. Wren (Mamie) had a lot happen to her and she was just swimming in her mind. Cal completed her. They are both broken in was that only the other can fix.....its beautiful.I hereby declare this book worthy of 3.75 stars.
