There's a third book?

I think I would have really liked Joanna and Antryg had I not already read Dragonsbane, which I feel has similar archetypes, but in a more interesting way. I haven't picked up on story tropes yet, since this is the only Hambly I've read outside of Dragonsbane (and its horrible, horrible, horrible sequels which I have attempted to scrub out of my mind). Hrm, will be interesting to read more.
