It's about secrets and truths unspoken. Feelings that have never been shared. This book begins with a wife finding a letter that she should open upon the death of her husband. What is in the letter? I found myself so engrossed in the lives the characters that at times I forgot about the letter. And then the author reveals the contents of the letter and WOW - the story just getst better. There are some unexpected twists and turns. I found myself appreciating the thoughts of some the characters - thoughts we have but never speak out loud.
