I read a children's bible (just for fun, wasn't religious), D'Aulaires' Book of Greek Myths, and World Tales (a collection of folk stories from around the world).

I also absolutely LOVED this random book called Paulus and the Acornmen:

I want to get it for the kids, but prices for old copies start at $250!! Maybe some day...

What were your favorite books as a child?
