One of the most influential works of C.S. Lewis is the Chronicles of Narnia which had been written from 1945 to 1951. The said works expressed different philosophical thoughts although targeted the young audience as judged on the plot which is mainly based on an adventure (Wilson, A. N. 206).One of the books in the series of Narnia is The Lion, the Witch, and the Wardrobe. It is a story about four children, namely Peter, Susan, Edmund, and Lucy and their adventures after the discovery that a wardrobe can lead them to a magic land called Narnia. The said children learned to resolve problems concerning different issues in the said magic land when they had to make a decision concerning betrayal and choosing for some form of survival through the test given by the wicked ruling White Witch that had trapped the land in a period of winter. The treachery done between the children shall be forgotten according to the White Witch and Spring will return if the Aslan, the lion will die (Lewis, The Lion…).Based on the plot of the said work by Lewis, it can be considered that the main subject matter of the story is the dilemma with regards to betrayal. This can be considered as the main reason why the said work is related and studied under the issue of moral development specifically since it can influence the children reading the story.In the succeeding adventure of the four English children, Prince Caspian: Return to Narnia, the story revolved in the battles being faced by Prince Caspian specifically with the Telmarines. They also helped in getting the Old Things along with the mouse Reepicheep (Lewis, Prince Caspian…).The story is about different issues such as the war between good and evil, friendship, betrayal and courage in facing different trials.
