I’ve heard good things about these books by Andrew Case:
Water of the Word: A practical prayer-book designed to help husbands intercede for their wives consistently and biblically.
Prayers of an Excellent Wife: A practical prayer-book designed to help wives intercede for their husbands consistently and biblically.
Setting Their Hope in God: A practical prayer-book designed to help parents intercede for their children consistently and biblically.
They are now available in pdf, Kindle, and other formats here for free.
