On a daring quest to save a life, two friends are hurled into another world, where an evil sorceress seeks to enslave them. But then the lion Aslan's song weaves itself into the fabric of a new land, a land that will be known as Narnia. And in Narnia, all things are possible.
The adventure begins in The Magician's Nephew, the first title in C. S. Lewis's classic fantasy series, which has captivated readers of all ages for over sixty years. This is a stand-alone novel, but if you want to encounter more of the wonders of Narnia, read The Lion, the Witch and the Wardrobe, the second book in The Chronicles of Narnia.
