Harve Bennett Book order (chronological)

Admiral James T. Kirk is charged by the Klingon Empire for the comandeering of a Klingon starship. The Federation honors the Klingon demands for extradition, and Kirk and the crew of the Starship Enterprise are drawn back to Earth. But their trip is interrupted by the appearance of a mysterious, all-powerful alien space probe. Suddenly, Kirk, Spock, McCoy and the rest of the crew must journey back through time to twentieth-century Earth to solve the mystery of the probe.

No One On The Enterprise Can Believe That Mr. Spock Is Gone! As the crew grieves for Mr. Spock, the awesome Genesis Device, now controlled by the Federation, has transformed an inert nebula into a new planet teeming with life. But Genisis can also destroy existing worlds. The creators of the Device want it given freely to the Galaxy. But Starfleet Command fears that it will become a force for evil. And the enemies of the Federation will not rest until they seize it -- as their most powerful weapon in the battle to conquer the Galaxy!
