The thing I have been focusing on in my story is they are being chased because he want the female for a hidden reason. My plans had been that he had a means of living for a much longer lifespan, not totally immortal, but close. She will live a longer than normal lifespan but her hubby won't, but what about their offspring, and the next generation. Are they going to inherit the ability to live longer? If not, then what is the reason to continue to move from town to town. To escape, run and hide is no longer needed.
Keeping it fresh is where I have been struggling, but if I switch to where they are hunting him, perhaps, or the going back to get information, then expose him, I could go with the military wants him for experimenting on and he will now be on the run, focusing more on keeping himself alive.
I've been stepping back from it, to allow my brain to focus elsewhere, instead of trying to get past the roadblock.
I'm writing down ideas to focus on later, adding notes as thoughts come up and doing more of planning it out then planning as I write it. I've started another story without a hidden agenda, and I think it has been of some help. With it, I am focusing on each town, not trying to plan out seven generations. Add to that the feedback I am getting from here and some fresh ideas are coming up.
If one generation is a doctor, another a scientist and another is in the military and reading the diaries of the founder of the family they should be able to put two and two together. They can find the hidden agenda and then set the government after him.
First generation is the founder. Second generation is a doctor. Third generation is scientist. Fourth generation is news star journalist who has access to the diaries. That heir can exposes him. Fifth generation is military who takes him for experimenting on. Sixth and seventh generation are having fun in the sun and enjoying the good life.
Has potential with what and who Mr. Big Bad dude is.
