"Love & War : Devotional for Couples" by John and Stasi Eldredge is a couples devotional designed to bring husband and wife closer together through a series of readings. These devotionals are very well written, and because they were penned by a husband and wife team, you feel like you are getting more of an unbiased voice, neither the husband or the wife.
The devotionals themselves are not extremely long - maybe three pages at most. Each devotional consists of a a quote that is relevant to the topic being discussed in that devotional, A short explanation of the subject matter and its relevancy, scriptural reference, short prayer, Bible verse, and then an exercise for couples to do together.
Overall, I found this devotional to be useful, and if nothing else, it does give you a special time each day to connect with your spouse over a short reading.
