Mrs. Bear asked what the proper order of The Chronicles of Narnia was, so here we go:
1. The Lion, the Witch, and the Wardrobe
2. Prince Caspian
3. The Voyage of the Dawn Treader
4. The Silver Chair
5. The Horse and His Boy
6. The Magician's Nephew
7. The Last Battle
Narnia needs to be entered through the wardrobe, just like Wonderland and the looking-glass. Then, after you've read the first four books, it's so fun to be dropped back into "The Golden Age" (golden ages are always visited from a sadder time--otherwise you wouldn't feel the goldenness as much). And almost at the very end, you're suddenly back where it all started, and mysteries from the first few books make more sense. If you read it in chronological order (which Sapientiae Amator--following his general trend to the perverse--insists is best), you lose a lot of the mystery and delight.
