Last week I read "The Shack".
It took me 3 days I think, to read it. It had such an interesting perspective that I still think about it.
It was sad and scary, then awesome, and then comforting. I read some of it, tissue in hand, because I cry a lot during good books and movies.
Read up on it and decide if you think it's for you. If you are interested, I really recommend it.
