Thanks to the wonderful Lisa at Eudaemonia and her post on Yearning, I can see where A Cornish House is going! I can see where the conflict is coming from and I can see the resolution.
When I split the manuscript up it became very clear that it was both women's stories. The word count was a bit heavier on Madde's side but that probably balances a bit the strength of Serena character - she comes across without the need for as many words. I had written in the first draft chunks from Mark's point of view but it was small and I think the book will be stronger if the story just comes from these two although Mark's own personal story is important and follows the same yaerning in a way. I don't think it needs to come from his voice if that makes sense.
So thanks to Lisa I am very clear on what these two women yearn for and on the obstacles in front of the them. What I now need to look at closely is the other things I have woven in incompletely (like C.S. Harris said in a comment yesterday - "I particularly hate those spots I skipped for some reason and now have to fill in." - hah what was I thinking at the time ) There are two key parts of the story that I have left incomplete and I need to decide if they are really necessary to the story or a just a distraction from it.
In the interim of course I will continue to chip away at my terrible typos.......
