The Federation faces extinction from an awesome new weapon!The Pandora Principle, by Carolyn Clowes, was the 49th novel published as part of Pocket Books's numbered series of TOS books, released in April 1990.

Description[edit | edit source]

A Romulan bird-of-prey mysteriously drifts over the Romulan Neutral Zone and into Federation territory. Captain Kirk and the crew of the Enterprise investigate, only to find the ship dead in space. When Starfleet orders the derelict ship brought to Earth for examination, the Enterprise returns home with perhaps her greatest prize.
But the bird-of-prey carries a dangerous cargo, a deadly force that is soon unleashed in the heart of the Federation. Suddenly, the only hope for the Federation's survival lies buried in the tortured memory of Commander Spock's protégée, a cadet named Saavik. Together, Spock and Saavik must return to the nightmare world of Saavik's birth—a planet called Hellguard, to discover the secret behind the Romulans' most deadly threat of all…

Summary[edit | edit source]

The Enterprise discovers a ship containing a dying Vulcan woman who Spock mind melds with. He secretly leads a group of Vulcan to Hellguard, a world in the Neutral Zone home to a group of half-Vulcan half-Romulan children, the products of rape who have been abandoned there. Spock insists they are integrated into Vulcan society and is given a year's leave from the Enterprise to raise one of them, Saavik, who eventually attends the Academy.

The Enterprise discovers a drifting Romulan ship with its crew dead, which was fitted with an unlimited cloaking device. They are ordered to bring the ship back to Earth. Kirk realises this is part of a scheme to return him to a ground assignment and tries to avoid it by sneaking into Starfleet Command to file a report in secret. However, two objects found on board the Romulan ship turn out to be filled with a contaminant that, upon released, destroys oxygen, killing everyone in Starfleet Command and the sealed Life City, except for Kirk who was sealed in the basement vault.

The Federation prepares for war, unaware the scheme was actually perpetrated by a secret Romulan cabal, the Twelve. Spock learns that Saavik saw the boxes containing the contaminant being prepared on Hellguard and gets permission to take thwe Enterprise there. En route, they take on board a Romulan smuggler, Achernar, who is actually working for Tahn, a disenchanted member of the Twelve.

Spock and Saavik beam down to Hellguard and encounter the architect of the scheme, which was tested on the parents of the children, but he commits suicide before they can get information from him. Spock plans to detonate a bomb in the store of the boxes and Saavik incapacitates him to plant it herself. They are both beamed aboard but not before the boxes are breached by the explosion, which sets off a chain reaction that destroys Hellguard.

Tahn and Achernar do a deal that sees the Twelve exposed while Than slips away. McCoy realises that Saavik survived exposure to the contaminant because of elements in the dust where they were stored and this is used to neutralise the contaminant on Earth. Kirk is allowed to remain as captain of the Enterprise for now.
