Josh (my fiance) and I started reading the book "A Purpose Driven Life" this past weekend. So far it has been really good! We have had long conversations each night after reading the book seperately. I think its really helping us to put God at the center of our relationship. I would highly recommend it to couples, it opens up a lot paths for discussion about general religious topics, not just stuff based on couples. Just thought I'd share, I like it a lot
