OK, when I read the seven books of Chronicle of Narnia, which order should I read them in?

Read them in published order. The magicians nephew was lame anyway, and it makes more sense to read the lion the witch and the wardrobe first. Then it's like going and back and being like, "Oh, that fits into the story. Neat." Also, the horse and his boy occured DURING the lion the witch and the wardrobe.
