Thunderlord is an unfinished sequel to Stormqueen!.

Thunderlord is at present only a couple of pages from Marion, continuing the story of Stormqueen! after Dorilys goes into stasis. This is far too little material for me to see where Marion might have been going with the story. Essentially, I would have to use her premise as a jumping off point and create the story entirely from there. Since I have 2 more in the "modern" Darkover under contract, I will do those first. What happens then depends on the wishes of the publisher and Trustee.
