The Lion, the Witch and the Wardrobe (C S Lewis)
It's a fantastic, really epic story, absolutely wonderful... I first read it as a child, and I still love it today. I hope you do, too.
Four adventurous siblings – Peter, Susan, Edmund, and Lucy Pevensie – step through a wardrobe door and into the land of Narnia, a land frozen in eternal winter and enslaved by the power of the White Witch.
But when almost all hope is lost, the return of the Great Lion, Aslan, signals a great change... and a great sacrifice.
