George MacDonald is considered one of the most important Christian authors of all time. His works include over twenty novels, many theological and critical works, and several volumes of poetry. But it is his stories for children that have endured the test of time. These works influenced many writers — including C.S. Lewis, who considered MacDonald his mentor, and J.R.R. Tolkien, who used MacDonald’s work as “a measuring stick” for his own writing in The Lord of the Rings.
