Rest in peace...
For me too, one of the first Star Trek books I had was the novelization for the Search for Spock in the summer of 1984. Honestly, it probably would have been her novelization of the Wrath of Khan earlier too. But Khan had scared the daylights out of me as a kid when I played the read a long book and record of the Wrath of Khan in 1982. It must have been the CETI EELS...

I recently read all of Vonda's novelizations last year in the ST II, III, AND IV OMNIBUS and bought them individually as well. Her writing style was incredible and the tension and fear of Khan's invasion of Regula station was akin to me a fierceness like Darth Vader or Negan just cold calculating and merciless with many dimensions. I felt afraid and fear of Khan all throughout the book. Her writing style elevated the movie novels to even greater heights.
To Mr. Cox as well, if Vonda personified Khan in a new way in her ST II, you sir took and amplified her work on Khan even more superbly and complemented it in your own way in the Khan novel to Live in hell. I read her ST II novel and your Khan book To live in hell back to back and it was an incredible experience. Thank you Mr. Cox too for adding to her personification and also showing readers a new and different side to Khan as well, 20 years later. My thanks to you as well. I miss her style as a novelist and her contributions to Trek and movie novelizations were unique and to be cherished, and will live forever. Her novelizations made great movies even greater with her uniqueness and style. Its sad that movie novels seem to be ending and dying.
Its my hope that Vonda's contributions to novelization hellp to bring back movie novelizations again. May she live forever in her works. She will be missed.
Rest in peace in ETERNAL LIGHT. My condolenses to you Mr. Cox and others as well.
I'm sorry for the long post.
