The Prometheus Design by Sondra Marshak and Myrna CulbreathCaptain Kirk and his crew are on a mission to investigate the mysterious wave of violence that has overtaken the Helvans — revolutions, mass riots, horrible tortures. This chaos is all part of an experiment by an unimaginable power that soon grips even the crew of the U.S.S. Enterprise.
Captain Kirk is plagued by violent hallucinations and removed from command. Spock takes charge but his orders seem irrational, even cruel.
Unless this terrible power can be stopped, not only the Starship Enterprise, but an entire galaxy will be ensnared in the deadly grip of the Prometheus Design.
