On a rainy cold morning, Polly and Digory decided to explore the attic of an old house. Their adventures began when they discovered Uncle Andrew's secret laboratory. Uncle Andrew tricked Polly into touching the magic ring, and she disappeared into the Other World. Digory was terrified and decided to go looking for Polly immediately. And he not only found her, but also heard with her the song of Aslan, the Great Lion, who created the magical world of Narnia, who created the sun, trees, flowers, herbs and talking animals. “This story is about what happened when your grandfather was little,” the author explains. "It is very important because without it you will not understand how the connection between our world and Narnia has been established."
