I picked up Young's The Shack first during its meteoric rise after it was published. For whatever reason I had trouble with it and eventually set it down. The Shack was made into a movie this spring and with its resurgent popularity, I figured it was a must read as I prepared to teach a class on the Trinity.
The youngest daughter of Mack, a middle aged man with an abusive past, is abducted and murdered early in the book. As Mack wrestles with God in the midst of this tragedy, he is invited to a remote shack by the Trinity. Mack spends a day with the Trinity (the Father represented by an African American woman, the Son by an Arab man, and the Holy Spirit by an Asian woman).
There are some really wonderful things about The Shack that make the book sparkle. It's no surprise to me that The Shack has made the impact it has in so many lives. The thing that drew me to the book-- its depiction of the Trinity--is at times well-articulated and emotionally touching.
