A seasoned SF or fantasy reader can't help but pick up on the strange cast of supporting characters, who could possibly be Satan, Mary, Joseph, Odin, Thor, or other more obscure mythical people. It's never stated, but the clues are there. It adds a clever extra layer to what was already an interesting, moving tale. A mashup of "To Kill A Mockingbird" and Neil Gaiman's "American Gods". Good stuff.
