Despite struggling with epilepsy and medications, David Barnes ("Faithful") combined his love for the Lord and his love of hiking in a thru-hike on the Appalachian Trail. Not only was it a maturing adventure, it was also a mission to be a witness for the God Who created such beauty. With determination and faith, he successfully made it south from Maine to Georgia. This book traces his steps day-by-day, providing some insights on what a thru-hiker may encounter on the A.T. and demonstrating how faith in God can help anyone "press on."
