Honestly, I could do without the new characters and just want to see the various crews interact with other crews. Fill the Enterprise-E's and Titan's command crew with officers from DS9 and Voyager. Station Janeway on DS9 to replace Ross, etc. We know the characters, and god, I miss the done in one novels.
This sounds like a fanwank idea embodying the essence of that which
Star Trek itself has been criticized many times before... Small Universe Syndrome.
But you have to walk into those knowing Picard got married, Worf's the XO. Just give us the occasional book where Data's alive and Worf's back on board. So post-What you leave behind and pre-Nemesis. Don't even bring up Worf being an ambassador.
Novels set within the timeline of the Television series itself are fine, and I'm sure many would and do enjoy those. I myself would not be counted among them however as I tend to find settings as fixed points both stagnant and arbitrary.
A window into the past that gives us insight into the present of a character would be great, but just showing up week after week waiting for someone to hit a reset button at the end of every adventure would grow tiring, quickly.
One of the reasons I continue to read Trek Lit now years later, is that the story moves forward. Things Happen. Consequences occur, events are shaped, and new circumstances are born as fruit of the whole process.
We know the characters, and god, I miss the done in one novels.
Don't worry. Some of us are still writing them, although mostly for TOS.
I've noticed this trend with TOS Books set during the 5YM, and to be honest it makes a sort of sense from a particular perspective, though I'm not drawn to these adventures like I am with the stories where new track is being laid.
I'm sure there's something to be said about picking up a random book and jumping in without having to really learn the lay of the land. You know all the characters already, you know the circumstances and all you really have to do is follow along. The literary equivalent of Law & Order.
I myself would prefer something more like Buffy:TVS or Babylon 5. Each "Season" deals with a particular overarching theme where each "Episode or Episode-arc" is somewhat self-contained, yet contributes to your understanding of the various characters and who they are, their motivations, and how they relate to each other and the larger story over time.
The difference between the two shows (for me) is this... I've seen maybe 20 episodes of Law & Order over the course of my life, they're enjoyable but they don't really lead anywhere. They're mostly forgettable. In contrast I've seen every season of Buffy & Babylon 5 (multiple times). There's a larger story there, the characters are fully realized and what happens early on plays into who they are, and how they change and grow later on.
If anything I'd love to see EVEN MORE of a shift towards this style of storytelling in Trek Lit. It keeps me interested and keeps me involved, and it keeps me coming back for more. I'd again just caution the creation of new characters without taking the time to fully realize and integrate them with the existing ones.
