The Lion, the Witch, and the Wardrobe

The Lion, the Witch and the Wardrobe is a book written by C. S. Lewis. It is set in an imaginary place called Narnia, where the main characters who are brothers and sisters are led into by the back of a wardrobe (closet). It is the second book by order in the Narnia series after "The Magician's Nephew", but is the first book published in the series.
Summary.
Peter, Susan, Edmund and Lucy Pevensie leave London during World War II to live in the country. While playing in the house, Lucy hides in a wardrobe. She finds that it leads to a different land. There, she meets a faun (half-goat, half-man) named Mr. Tumnus. While having tea, he tells her that the land is called Narnia. It is ruled by the White Witch, who makes it always winter, but never Christmas. When Lucy returns to the wardrobe after many hours, she finds that only a few seconds have passed in England. Her brothers and sister do not believe her and the wardrobe has closed so they cannot go into Narnia. 
Many weeks later, Lucy comes back to the wardrobe during a game of hide-and-seek. Edmund follows her into Narnia, but cannot find her. Instead, he meets a lady. She says she is the Queen of Narnia and gives him Turkish Delight. She promises to make him prince if he will bring the other children to her castle. After she leaves, Edmund finds Lucy. When she talks about the White Witch, he thinks that it is the lady he met. When they get back to England, Edmund lies to Peter and Susan and says they did not go to Narnia. This makes Lucy upset. 
Later, they are all hiding from the housekeeper and go into the wardrobe. This time they all go into Narnia. When Lucy leads them to Tumnus's cave, they find that he is arrested and his cave destroyed. Two talking beavers shelter the children. They also tell them about a prophecy that the witch will fail when two Sons of Adam (human males) and two Daughters of Eve (human females) sit on the thrones at Cair Paravel, Narnia's ruling castle. The beavers also tell them about Aslan, the true king of Narnia. He is a great lion and has been gone for many years, but has come back. 
Edmund sneaks away to go to the witch. When they find out, the children and beavers go to find Aslan. The witch is mean to Edmund because he did not bring his siblings and leaves to chase them. The winter is starting to warm into spring and she is stopped by the thaw. The children find Aslan and rescue Edmund just before the witch kills him. He is very sorry for following her. The witch says that Edmund must be given back to her because of an old law. The law says that all traitors (people who break trust) belong to her. Aslan gives himself in place. He is killed, but comes back to life through an even older law. This one says that if someone who has not committed the crime willingly takes the punishment, he will come back to life. 
In a big fight, the witch is killed by Aslan. The children are kings and queens in Narnia for 15 years, growing into adults. Then they return to England through the wardrobe and are kids again. No time has passed.
