I think my favorite is "Who Is Coming to Our House?" by Ashley Wolff
I'm always in search of a few nice books that relate the Christmas story without heavy use of "Our Lord/ Our Savior". Personally, I feel that the birth of Christ is worth celebrating, and we also celebrate the Solstice and understand the origins of the trappings of the season. So, I want the story without all the religious lingo. Don't mind bringing angels and God into it, but I'd like to downplay the rest.
What are your favorites, for any age?
