Chronicles of Narnia by C. Lewis - A wardrobe leading to the kingdom of Narnia brings four children face to face with the evil White Witch and Aslan the lion-king who leads the fight against her. (Levels T - U)
I took Zimbio's 'Chronicles of Narnia' quiz, and I'm Susan Pevensie! I also think I've got some Lucy in me - I'd probably have believed her about the wardrobe in the first place. I also wouldn't stop believing in Narnia.
