There was a plan to novelize the script that Dorothy Fontana wrote. But I'm not sure if it ever got off the ground.
Earlier this year, Fontana had this to say about it:
It was a very complicated story. It was big.There was mystery. There was a chase. There was threat and danger. It was five parts that were really very full and complicated. The ‘Vulcan Fury’ was actually one of the moons of Vulcan that was actually a weapons platform that had long bead dead and some happens tore-activate it. Which would then threaten the Enterprise which was in orbit and other Federation ships. The problem was that it became very expensive and the head of [game publisher] Interplay pulled it because it was too expensive and he didn’t see getting his money back on it. I have asked [CBS Products Exec] Paula Block if I can take it, clear it,and make it into a novel. I haven’t got an answer back yet, but I think it would be a heck of a great story as a novel.
