Not certain what I think about the Una designation. Do find interesting the first part of April's section. How did you decide which officers to take from previous novels, Greg?
Mostly, I went back and reread my old April story from years ago, which took its cues from Diane Carey's earlier novels, but we also had to invent some new crew members to serve our own plot. I wanted to keep the emphasis on Una and April, plus our new characters, so I only used the other crew members as required by the plot, the communications officer, the helmsman, the first officer, etc.
And, of course, you can't write April without including his wife in the story.
