Our hero trio come to New Eden, apparently deserted but for a single young woman, Lisa, who is traumatized into speechlessness. She rapidly recovers and starts manipulating the trio, setting them against each other. Unbeknownst to them, they have wandered into a social experiment run by two scientists: Dr Asgard, an Ayn Rand type who thinks humans are basically selfish, and Dr Diana, who thinks they’re basically compassionate.
The whole thing plays out rather like a multi-way cross between Blake’s 7: Duel, Star Trek: The Empath and any given episode of The Prisoner, and as such it’s actually not too bad, for The Starlost values of “not too bad” of course. Of course Dr Diana’s view eventually triumphs as the hero trio demonstrate that their love for each other is transcendent and self-sacrificing, but we do actually get a little time to explore Garth’s ambivalent feelings about being the third wheel to Devon and Rachel’s romance, and there’s a suggestion that Rachel’s puritanical upbringing means she’s a little suspicious of men in general, even ones she likes, which wouldn’t be too surprising.
Drawbacks: the message is iterated over and over in declamatory speeches between Asgard and Diana, to the point where I was groaning every time the story cut away to them. Also, while we do actually get an older woman with agency in this story in the form of Dr Diana, the gender politics are still mighty sketchy: of course it’s the Woman Scientist who is all about Compassion and Love, and the Delilah trope with Lisa is more than a little misogynous.
