Publisher's description[]

Teaser page
An innocent scientific expedition becomes a subterranean nightmare when Captain Kirk and the crew of the Enterprise find themselves racing against the clock of their own executions.


Captain's log: star date 19:27.4. On routine mineral and biological survey of space sector 179, sub-sector 23-C...

Spock observed that planet Alpha 23-C was rich in industrial minerals, so Kirk, Leonard McCoy and Montgomery Scott beamed down to conduct an overnight topographical survey. The trio split up to climb a plateau. Scott spotted a beautiful outcropping of gemstones that he thought would make a good necklace for a woman he liked, but before he could chop off a sample with a pick axe, it shot him with a laser beam. Peering into one gem, he was strangely psychoanalyzed — facets reflected various sides of his personality, including fantasies as a heroic Highlander and secret agent as well as images of himself terrified by witches as a child. He yelled before passing out. Kirk revived him, then found McCoy in hysterics.

When they camped that evening, Kirk awoke in paranoia and began strangling Scott. McCoy stirred and quickly stunned Kirk. Realizing they weren't prepared for this type of psychological assault, Kirk decided to return to the Enterprise, but their communicator signals were jammed. Suddenly a bipedal crystalline lifeform approached. Scott reached for his phaser but the being, named Izor, fired a laser beam from its head and disarmed him. It called the landing party kidnappers and attempted murderers, revealing that the crystal gems were its species' infants. Kirk surreptitiously dropped his communicator as Izor led them into deep caverns.

Captain's log: star date 19:27.5. Mr. Spock's "sophisticated crystals" have turned out to be living things! And we are being marched to their underground civilization!

They emerged into an underground crystal city paradise populated with the crystal lifeforms. Despite Kirk's protest of innocence, their president condemned the humans to die. Later they were brought back to the president's office. Kirk observed from a periscope that Spock had beamed down and begun to inspect the gemstones. However, the infants reflected only geometric images, unable to spark emotions from the Vulcan. Nonetheless, Spock was captured and reunited with the landing party.

The president could not read their minds to confirm that they were innocent, as only their children had strong telepathy. Suddenly a large crystalline dinosaur, a rampaging slourda, disturbed the city's peace, retreating tentatively when spears were thrown at it. The dragon was immune to natives' thoughts which generated laser beams, as people were from repeated exposure to bacteria, but Kirk believed that he, Spock, Scott and McCoy could act like foreign germs. Spock proposed to channel new thoughts through one of the crystal infants, but it meant carrying a baby gem into danger. When they next encountered the slourda, Spock was able to project scientific concepts though the gem such as the formula of sulfuric acid, E=MC2, Newton's Third Law of Motion, and theories behind rocket engines, which shattered the dragon into pieces.

Having demonstrated their good intentions, the landing party was allowed to leave. Kirk and Spock provided the natives with scientific texts to produce enough new thoughts to keep them free of slourda forever.
