The Shack by William P. Young. From Amazon: "Mackenzie Allen Philips' youngest daughter, Missy, has been abducted during a family vacation and evidence that she may have been brutally murdered is found in an abandoned shack deep in the Oregon wilderness. Four years later … Mack receives a suspicious note, apparently from God, inviting him back to that shack for a weekend… What he finds there will change Mack's world forever. In a world where religion seems to grow increasingly irrelevant "The Shack" wrestles with the timeless question, 'Where is God in a world so filled with unspeakable pain?'
