I don't know if you have seen the movie The Vow, but whatever your answer is I want to encourage you to read the book. I don't think the movie does the book justice.
The Vow is actually a great book about the real couple, Kim and Krisxan Carpenter, and their story of finding love for each other again. They were involved in a serious car accident that left Krisxan in a coma. She will never remember the first time she met her husband, got married, and their honeymoon. Through it all it is a story of vows, God's miracles, promises, and path for their lives. Kim and Krisxan are truly an inspiration and the best true story I have read.
I suggest you read it! You won't regret it. However some parts are very difficult to read.
