The Chronicles of Narnia - The Lion, the Witch, and the Wardrobe Official Illustrated Movie Companion

I read the entire series at least 7 times as a young teen and I still care enough to argue passionately on the subject of book order.

I love this series as a whole. I like some of the books better than others, but even in my lesser favorites, there's at least one thing which stands out and makes me think fondly of it.
