My youngest brother recommended The Shack and I read it in one sitting it was so captivating. The beginning of the book is a little tough to get through because it is pretty sad, but once you get through that the rest of the book is an interesting look at God and Spirituality wrapped into an engaging story line. It is definitely worth reading just for the different point of view!

Here is another review on it that I felt gets the point across.
Finally! A guy-meets-god novel that has literary integrity and spiritual daring. The Shack cuts through the clichés of both religion and bad writing to reveal something compelling and beautiful about life’s integral dance with the divine. This story reads like a prayer—like the best kinds of prayer, filled with sweat and wonder and transparency and surprise. When I read it, I felt like I was fellowshipping with God. If you read one work of fiction this year, let this be it. -Mike Morrell, Zoecarnate.com
