Stupid quizzy quizness.
The sixth book written, you're nevertheless the first chronologically. You not only describe the creation of Narnia and tell where the White Witch, the lampost and the wardrobe came from, you get to bounce between worlds with the help of Uncle Andrew's weird magic rings.
Find out which Chronicles of Narnia book you are.
Given that this is my favorite of the whole pack of the books... I'm pleased by this. :)
