Child of Two Worlds
(Star Trek: The Original Series)
by Greg Cox

A young Spock is science officer on the U.S.S. Enterprise, with Captain Christopher Pike. When an outbreak of deadly Rigelian fever threatens the crew it’s off to find a cure. But things take a turn when the Enterprise rescues two young women.

Soon the Enterprise crew are stuck between a planet with a needed resource and a demand, and the Klingons.

Greg Cox does no disappoint in this tense story where there are no easy solutions. And he manages to add themes of cultural identities. One of the best Star Trek novels.
