In previous books respected New York pastor and bestselling author Timothy Keller has looked at such diverse and topical subjects as the existence of God, our need to do justice, the meaning of Jesus' life, and the human temptation to make idols - all through the twin lenses of a biblical framework and an engagement with contemporary culture.

In this new book, co-authored with his wife, Kathy, he turns his attention to that most complex of matters: our need for love, and its expression in marriage.

Beginning with the biblical narrative, and its pictures of marriage that span the original ideal to the broken to the redemptive, he looks at themes of friendship and commitment; the completion of men and women in each other; singleness, sex and divorce; and ministry and discipleship within the context of marriage.

This is a profound and engaging work that will challenge and inspire people in all stages of life - single, newlywed and married.
