The Shack

So this far the author is writing for his friend mack.  Macks daughter was kidnapped and murdered while camping, and they found her body in "the shack". This was a really emotional part because Mack left her there while trying to help his son. A while later he recieves a a letter in the mail from a guy named "papa" telling mack to meet him in the shack. The name papa is significant because thats what macks wife nan calls God. So hes really shaken up about it. However, there is something in the back of his mind that wants to know who this papa is and why he told him to meet him in the shack. He has an internal battle thinking that maybe he could find closure of some sort.
