I like Michael Jan Friedman's novelization of "Relics" far more than the actual episode. The episode is, for me, something of a misfire, and the novelization at least tries to fix the episode's major failing -- they found a Dyson Sphere, and they do absolutely nothing with it. My feeling on "Relics" is, "You wasted a Dyson Sphere on a b-plot. You could have spent six episodes on a Dyson Sphere. And you relegated it to damn b-plot."
Yes, they go inside in the episode and there's some false drama that's confined to the ship when they do, but there's no exploration whatsoever of this Big Damn Object. Friedman at least sends an Away Team to the surface, where they don't do much of anything, but it's something!
On top of that, most everyone acts wildly out of character, and the ending amounts to shoving Scotty out the door at the earliest opportunity. I don't expect the crew to fawn over Scotty -- to be honest, he and the "Gang of Four" were not characters I really cared much about one way or the other -- but they don't have to be jackhats.
I know the episode's beloved but, for me, "Relics" is a misfire.
