In The Magician's Nephew, the first novel in the Chronicles of Narnia series, C.S. Lewis uses a straightforward story arc. Chapter 1 provides the exposition in which the setting and characters are introduced. The time period is given in the first paragraph as "long ago when your grandfather was a child" and is further described in the second paragraph as when "Sherlock Holmes was still living in Baker Street." The location is London in "a long row of houses which were all joined together." We then meet Polly Plummer and Digory Kirke, the two main characters.
The rising action also begins in Chapter 1 when Uncle Andrew locks the children in his study. Polly touches one of the humming rings and disappears. The rising action then continues as Digory uses a ring and ends up where Polly is. They visit the world of Charn, where Digory rings the bell that awakens Queen Jadis. The action continues to rise as Jadis causes trouble in our world and in the newly created world of Narnia.
The climax occurs when Jadis tempts Digory to eat the apple and/or take it back to his mother. Digory's head suddenly clears, and he leaves the witch and returns to Aslan with the apple.
In the falling action, Aslan praises Digory for his obedience, King Frank and Queen Helen are crowned, and Aslan puts Uncle Andrew to sleep. A beautiful tree springs up that will be Narnia's shield. Digory confesses to Aslan how he was tempted, and Aslan lets Digory pluck an apple to take back to his mother.
The resolution occurs when Digory gives the apple...
to his mother and she recovers. This resolves Digory's first problem in the story, which was his deep sorrow over his mother's terminal illness. Other loose ends are tied up as well, with Narnia experiencing hundreds of years of peace, Uncle Andrew giving up magic, and the tree that grew from Aslan's apple being made into a wardrobe--which becomes the way into Narnia in the second book.
