By Jane Land. Spock and Christine are stranded on a planet with a paleolithic technology level, they have to adapt to the local culture and a relationship develops between them.
Kista is "...an attempt to rescue one of Star Trek's female characters from an artificially imposed case of foolishness. Try to think objectively for a minute about what we know of Christine Chapel's background, education, accomplishments... and you will come up with a far more interesting character than she was ever allowed to be...I like her. I hope you do too."
