the Shack (fiction) William P Young
this powerful novel explores pain, loss and forgiveness, learning to live in the Father's love, and more all in a compelling hard-to-put-down, masterfully-told story.  One of the most powerful books I've read in a long time, especially for those yearning for true freedom and wrestling with what it means to be a Christian (click here to Kyle's response to an email criticism of "the Shack")
