in order?
The Lion, the Witch and the Wardrobe; Prince Caspian; The Voyage of the Dawn Treader; The Silver Chair, The Horse and His Boy; The Last Battle; and The Magician's Nephew. though really The Magician's Nephew you should read right before or right after Lion Witch and the Wardrobe.
they're by C.S. Lewis
Makia mentioned them...must've missed it.
1.) Magician's Nephew * It is really the first book that explains how Narnia came to be but it is also number 7.
2.) Lion Witch and the Wardrobe
3.)Prince Caspian
4.)The Voyage of the Dawn Treader
5.)The Silver Chair
6.)The Horse and His Boy
7.) The Last Battle
They are all by C.S. Lewis, J.R.R. Tokkiens friend.
