Hi Marvin. In the Eugenics Wars series, the first of which is on Bookshare, Gary Seven and Roberta are the main characters, and Captain Kirk and the Enterprise are part of a second plot line. However, in that book there is reference to an adventure like you described. I suspect this was actually an episode of the original series TV show. James Blish took all of those episodes and adapted them to make short stories. His adaptations are on Bookshare, there were originally twelve volumes but they were collected into two larger ones. If there was an episode like you described it would be in one of those collections. I never saw more than a few of the original episodes, but I've read many of these adaptations and I think they are rather nicely done. Hth, Kellie
