Yes, this is the plot of the new episode of Star Trek: Strange New Worlds, but it's also the plot of my 2001 Star Trek Novel, "Do Comets Dream?" which is itself vaguely adapted from a tale told in my Inquestor series, "The Comet That Cried for Its Mother", originally published in AMAZING.
I went in to the ST:TNG offices to pitch to them in the 1990s and I pitched this story. They looked at me and said, "Your idea is good, Somtow, but it's simply too imaginative for us."
No hard feelings. Instead, I pitched it to John Ordover at S&S, and they bought my story as a Star Trek novel instead.
It was not the most popular Star Trek novel — half the fans loved it and the other thought it was "simply horrible" — perhaps because they detected a faintly ironic tone about the storytelling, which is, after all, a major feature of my style.
So, lest you think I'm bitching about this, not at all. I think it's rather flattering. There's no question of "plagiarism" — when you work for them it's work-for-hire, so they own it anyway.
However, I was thinking that now that it seems to be okay to use ideas that were "too imaginative" 30 years ago, maybe they should consider hiring me. In my old age, it would be nice to write another Star Trek story before I croak. To quote a certain ex-President ... "Paramount - if you're listening -" Call my agent, Judy Coppage.
