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.

Harry lives on a farm and loves to help Daddy. Matilda the cow is going to have a calf, and Harry is very excited. But when Snowy the pure white calf steps out into the snow, Harry can’t understand why she looks so dirty! In this story, Harry learns that even though our sins are like a bright red stain, God can wash us and make us whiter than snow.
