The only thing I don't like about this story is the portrayal of the Unitarian minister. I'm not sure what they were like twenty years ago, but their motto nowadays is pretty much "everyone is welcome." (Except longer and more complicated.) I found their apparent shock at the Amazon's lesbianness particularly bothersome, because the current reverend at the Unitarian church in my town is lesbian and nobody gives a damn. It's not really a huge deal, I guess, just one of those little details that really bother me.
I really love the Lois/Diana interactions, though. They need to interact more.
