Star Trek Adventures - Spock Must Die!

It is widely recognized as the first original Star Trek novel written for an adult audience, following a previous young reader novel titled Mission to Horatius.

The author incorporated background details about Dr. McCoy, such as his divorce and his daughter Joanna, which were drawn from the series production bible and subsequently adopted by other writers in the franchise.

Unlike the author's earlier contributions which were adaptations of existing television scripts, this was an original narrative written specifically for the book format.
