I totally loved it! I had pretty high expectations and this book actually met my expectations. I've read this book as a buddy read, so I couldn't fly through it. Otherwise, I'm sure I would have read it in just a few days. This book was so engaging, I really wanted to know who wrote the fifth letter, just as Joni did. The ending was really not what I expected, even though I kind of guessed who wrote the fifth letter. I would really recommend reading this book as it is well written and really engaging.
