Sunday school prize-giving suggestion for 9-14 year olds

A modern account of Muller's life. Somewhat trite and lacking, but one would like modern children to read what was done for abused and orphaned children of those days. It becomes more spiritual and touching by the end. There is too little said about Muller's conversion, but more is said about his gratitude to the Saviour. Trailblazers series.
