A ‘Star Trek’ novel was published depicting Kirk and Spock as gay lovers. ‘Killing Time’ (1985) included “slash” (same-sex) themes that were supposed to be edited out, but the wrong version was printed. The publisher could not recall all copies sent to stores, and fans quickly bought them.

The author was well known in the fan community for publishing very explicit [Kirk/Spock slash fan fiction](https://en.wikipedia.org/wiki/Kirk/Spock). From [Wikipedia](https://en.wikipedia.org/wiki/Killing_Time_(Star_Trek_novel\)):
>*Killing Time* is a *Star Trek: The Original Series* novel written by Della Van Hise and published by Pocket Books in 1985. The original manuscript had Kirk/Spock slash fiction elements, and these were requested to be removed by Paramount. However, they were not removed, and 250,000 copies were printed. These romantic undertones between Spock and James T. Kirk were brought to the attention of the office of the creator of *Star Trek*, Gene Roddenberry, who made Pocket Books recall the first edition. This edition subsequently became a collector’s item, with more than fifty changes made to a revised version.
