My husband checked out from our town library,

there is a brother book "the power of praying hu*****and".
My hu*****and and I are reading together.

There is another set of book, called "A woman (man) after God's own heart", very good as well.

Also "The love Dare"(it says it's a #1 new york times best seller) is a day to day guide to refresh love to (old) marriage, from the movie Fireproof. The movie is done by a church, everyone is amature except the main hero, and it was the hit in the movie theatre when it came out.
