No, that's not my living situation. I'm in a very, very nice apartment in downtown Fes for the next 2 months. The Shack is the name of the book my host sister Ghizlane is reading. Amazon's description:
"Mackenzie Allen Phillips's 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, in this midst of his great sadness, Mack receives a suspicious note, apparently from God, inviting him back to that shack for a weekend. Against his better judgment he arrives at the shack on wintry afternoon and walks back into his darkest nightmare. What he finds there will change his life forever."
I don't know where she heard about the book, but I do know she had no idea someone from Oregon was coming to visit, and the protagonist lives in the Willamette Valley, and "the shack" itself is located near Wallowa Lake.
