The Lion, the Witch and the Wardrobe

I didn't read any of the Narnia series as a kid, but what a ride it's been reading it to my daughter.

The story and world building is brilliant, but not as heavy as deep fantasy. The characters are layered even though you don't get a lot of time with them given how many are introduced.

The Magicians Nephew is a great start, but the Lion the Witch and the Wardrobe takes it up a level!
