Description (enemy-free B&N version)
With only prayer and a faith that always seemed too small, Audra Grace Shelby departed with her husband and children on a one-way flight to Yemen...deep into the heart of conservative Islam.
With honesty and passion, she shares her harrowing journey as a Christian woman thrust into a culture dangerously different from her own. From the friendships she forged, to her gnawing doubt and fear, to her offers of hope when her new friends' religion failed them, she gives us glimpses of a world most have never seen: behind the veils of real Muslim women--and how the grace of God touches lives in the midst of an Islamic stronghold.
