Remember Saavik? Saavik was a really cool character. I can’t remember when I saw Saavik’s official first appearance in the Star Trek canon, which was in The Wrath of Khan. But I do remember reading about her in Carolyn Clowes’ 1990 novel, The Pandora Principle, which is a ripping Girls’ Own Adventure yarn, in the style of Heinlein’s juvenilia. This came out when I was 14, and I probably bought it in the same year, which was definitely well before I saw The Search for Spock. I picked it up again because the plot involves Vulcan trafficking.
The other examples of Vulcan trafficking in my recent reading have focused on Romulan efforts to exploit Vulcans’ telepathic powers. The Romulans are alert to every possible advantage that could forward their political and diplomatic ambitions, and the Vulcans are surprisingly lackadaisical about looking for missing exploratory and trade vessels and keeping track of areas where such vessels tend to disappear.
