Message in a Bottle by Nicholas Sparks. Great movie too starring Kevin Costner & Robin Wright. Hard to believe this was the first book to become a movie. Luckily, 'A Walk to Remember' & 'The Notebook' followed :D
Read this book a year or so back even though I've seen the movie a long time ago. Just like The Last Song, I was able to recall Kevin Costner's character weaved through his sorrows and joy. I bawled towards the end eventhough I knew what was coming.
The Notebook is about a man who reads to an old woman he visits from a faded notebook that tells the story of a couple who are separated by World War II, then passionately reunited years later.
