Review:

By spending just "10 minutes a day" going through this book with your spouse, your communication and marriage are bound to improve.
Sometimes, going through the questions can take more than 10 minutes, but I suppose its up to yourself how much time you want to invest in your marriage.
The book is filled with thought provoking anecdotes and the reassurance that you are not the only ones feeling the way you do. If you are interested in improving your marriage, then try this book!
