When young, expat businessman Jack Troughton's girlfriend tells him about the Bible she found on a Cheltenham bench, his life is turned upside down. Challenged by Celia's faith, and brought face-to-face with terrifying Estonian sex-traffickers when tragedy strikes, his response impacts countless lives and threatens all he holds most dear.

But Celia was not the only one to come across a Bible that day. A PR guru and a Ghanaian care-worker are among others who are impacted by the discoveries that will revolutionise their lives and heal painful wounds.

Moving swiftly from Tallinn to the Cotswolds, and from Glasgow to New York, the disparate characters' lives begin to interweave as they share new-found faith and ask who left the precious books for them to find.

Four is a faith-filled thriller embracing the pain of loss and inspiring with all God can do to redeem and restore.
