Wopsy is the story of a very young Guardian Angel, sent to watch over a pagan baby in Africa. Wopsy desperately wants his baby's soul to become white and clean in baptism, but what is a small guardian angel to do when there is no missionary priest in the village?

The author was a member of the missionary order of priests known as the White Fathers (So named because of the white habits they wore). He wrote the "Wopsy" series of books in order to encourage missionary vocations in young children. (Summary by Maria Therese)
