Questions for Carrie Bebris keep popping into my head at odd intervals, though they're much more mundane than yours about fire opals! There's so much detail about things that are foreign to me, which is why I've googled a couple of them myself.

It's a little odd for me to put this much thought into a book of this genre. I read lots and lots of mysteries, but I usually just drink them in and enjoy. Ditto for JA sequels. But because of the GR, I'm reading more slowly, going back to look at things again and actually even looking up related topics.

Add that to the discussion with all you clever people and it makes for a most satisfying read, don't you think? :-)
