Search Worlds Without End

The Shaddan Crown is the key to power -- and the Klingons have the advantage!

An Enterprise shuttle is forced to crash-land in a violent storm on the barren planet Sigma 1212. Spock, McCoy and Kailyn, the beautiful heir to the Shaddan throne, survive in the near disaster.

Pursued by primitive hunters and a band of Klingon scouts, they must reach the mountain where the fabulous dynastic crown is hidden. With the help of Spock and McCoy, and her own fantastic mental powers, Kailyn must prove that she alone is the true heir to the throne.

Should they fail, they will open the door for Klingon takeover of the whole quadrant -- and the galaxy's hope to live long and prosper will fall in the shadow of a cruel tyranny.

A routine diplomatic visit to the water-world of Akkalla becomes a nightmarish search for a missing Spock and Chekov, a search that plunges Admiral Kirk headlong into a corrupt government's desperate struggle to retain power.

For both a Federation Science outpost and Akkalla's valiant freedom fighters have begun uncovering the ancient secrets hidden beneath her tranquil oceans... secrets which, when exposed, may even mean civil war for the people of Akkalla -- and death for the crew of the Starship Enterprise.

When the planet Empyrea, a colony of genetically perfected human beings, demands that the Federation remove a science station which has been in place for nearly twenty years, the Starship Enterprise is assigned to transport to the planet the Federation ambassador who negotiated with the Empyreans long ago -- an ambassador who was once Dr. McCoy's closest friend, but is now a bitter rival.

On Empyrea, McCoy discovers Anna, a daughter he never knew he had. McCoy soon realizes that the isolationist Empyreans must not learn that her father is an off-worlder, and that her genes are less than "perfect". As relations with the Empyreans collapse around him, McCoy must find a way to save his newfound daughter from the harshest penalty her planet can impose.
