The Shack: Where Tragedy Confronts Eternity » (First Edition, Unabridged)

Wm. Paul Young was born a Canadian and raised among a Stone Age tribe by his missionary parents in the highlands of former New Guinea. He suffered great loss as a child and young adult and now enjoys the "wastefulness of grace" with his family in the Pacific Northwest.

A kidnapped daughter is presumed dead, and when her grieving father receives a letter, apparently from God, inviting him to the scene of the crime, he can't help but go.  What he finds there will change his world forever.
