Lilith Saintcrow wrote a steampunk mystery novel that was published back in November. Thanks to Nano, I didn't get to read it, but I've finally found the time. The Iron Wyrm Affair presents an alternate London (which seems to be a big deal in steampunk...) in which magic has flipped the Industrial Revolution all around. Ms. Bannon is a sorceress in service to the Queen and her mission is to protect Archibald Clare, one of the great minds called mentaths. However, conpiracies killing off both mentaths and sorcerers may just get them killed, or it may just turn them against the Queen. Oh, did I forget to mention? The two of them can't stand each other.
