With a focus on a young wife who, on a long plane trip meets a man named "Jay" who knows way too much about her and helps her come to grasp with her husband's recent conversion to Christianity (is the symbolism obvious enough?), this book makes one main point and that is God's desire for a personal relationship with each of us. Furthering on that, the emphasis is that we, and God, are not "complete" until that relationship is there.
It reminded me a bit of The Shack but in a much simpler format.
I am not sure how well this book would relate to someone who is not yet on any sort of faith journey but it should be enjoyed by someone who is trying to figure out what Christianity is all about, or someone who considers themselves to be Christian but is still searching for something more.
This book resonated me because I am just coming out of a season of my life where stress, anxiety and fatigue kept me from working on the relationship that God wants with me. I clearly see now what was happening and I was indeed missing and feeling incomplete without that relationship.
