The Harry series is suitable for pre-schoolers and early school-aged children and is about a young boy called Harry who lives on a farm. Each book is based on a Bible story or verse and contains a clear, yet simple gospel message. The accompanying illustrations of the whimsical countryside scenes are hand drawn by Mary Weatherup, who lives on a farm in rural Northern Ireland. In this book, Harry sets out with his father to find the lost sheep. Harry learns lessons from the Bible that he is like the lost sheep, but the Lord Jesus came into this world to save lost sinners like him. This story is accompanied with full colour illustrations.
