From rags to riches
I’ve gone from having a neat universe with no story to having a little short story to having the potential for a book. One of the biggest problems with action adventures is how many times can the hero save the world? Either you have to get new villains (more powerful natch), do the city -> state -> nation -> world -> solar system -> galaxy -> universe scaling, etc.
For me, the book would be the journey of the Spacers and The Dizzy Dean caretaker crew to the new system and their decision to leave. Of interest would be what got Jenny to go with the Spacers, how she learned to interact with them, how she influenced their culture to form the basis of the Clans, how the crew of the XXX (including how/why the iconoclastic YYY capitulated) got on The Dizzy Dean, how the two crews interacted, etc.
In short, the journey is the destination and the story.
