Guy Stagg spent 10 months walking from Canterbury to Jerusalem, following medieval pilgrim paths across 5,500 km.
He began the journey after several years of mental illness, hoping that the walk would heal him. A non-believer, he wanted to understand religion by taking part in its rituals.
The Crossway, published by Picador, is an account of his journey, a mix of travel and memoir, history and current affairs.
Guy came into Church Times offices to talk about his extraordinary journey. The Crossway is available to buy from the Church House Bookshop.
