Interesting. A historical PNR with dragons.
The h inadvertently finds out what the H is by virtue of inviting herself over to visit with the housekeeper. She's working class...actually, that might be a stretch seeing as how some of her siblings are maids, etc. So there is class disparity between her and the H - who is titled. That said, I get the feeling that where dragons are concerned, it's less who's appropriate and more who will adapt.
She has attitude - he calls her Cerberus more often than her name. I thought that a bit odd considering said class disparity. Also thought it odd that the H would back off. Then again, perhaps the attraction was behind that.
Eventually the bad guy figured out how to separate them and grabbed her. The H went after him with a good deal of interest, showing him for sure what he was but he didn't come out of that confrontation alive.
I think...I may pursue this one further.
