By C S Lewis
"The Lion, the Witch and the Wardrobe is a fantasy novel for children by C. S. Lewis. Published in 1950 and set circa 1940, it is the first-published book of The Chronicles of Narnia and is the best known book of the series. Although it was written and published first, it is second in the series' internal chronological order, after The Magician's Nephew. Time magazine included the novel in its TIME 100 Best English-language Novels from 1923 to 2005. It has also been published in 47 foreign languages.
Lewis dedicated the book to his god-daughter, Lucy Barfield."
"The story begins in 1940 during World War II, when four siblings--Peter, Susan, Edmund, and Lucy Pevensie--are evacuated from London to escape the Blitz. They are sent to live with Professor Digory Kirke, who lives in a country house in the English countryside.
While the four children are exploring the house, Lucy looks into a wardrobe and discovers a portal to a magical world named Narnia. There she meets a faun named Tumnus. He invites her to tea in his home. There he confesses he planned to report her to the tyrannical White Witch but has thought better of it. Upon returning to our world, Lucy's siblings do not believe her story about Narnia."
