2026/056: The Luminous Dead — Caitlin Starling

“That was the look of somebody resigned to being the monster they knew they were.”

Gyre lives on Cassandra-5, a planet with immense mineral wealth but little else to commend it. She takes a contract to explore a particular cave system -- dangerous, because the caves are often collapsed by native beasts called Tunnellers -- which will pay enough money for her to get off-world and search for her mother. She's been surgically fitted into a life-support suit, and she expects to find a full team supporting her by comms. Instead, she gets a single person: a woman named Em.

Neither Gyre nor Em has been wholly honest. Gyre's lied about her experience: Em hasn't revealed the true purpose of the mission, or the number of failed (and fatal) attempts already made. But it's Em who's in the position of power. She can order Gyre's suit to dispense drugs, sedating her: she can even manipulate the suit remotely, dragging Gyre along.

In the darkness of the caves, Gyre keeps feeling that she's not alone. That she's being watched. And she catches glimpses of things that can't be there -- that Em assures her aren't there. But she can't trust Em...

This is an immensely claustrophobic novel: Gyre imprisoned in her suit, unable even to touch her own skin; repetitive conversations between Em and Gyre; the physical dangers of the cave, and the possibility that Gyre has been exposed to something psychotropic. Gyre has no friends, and only the memory of her mother to motivate her. Em is an orphan, who's sent many to their deaths and seems likely to do the same to Gyre.

I found this slow, and often repetitive. There are only so many sumps Gyre could swim through before it felt tedious: there are only so many arguments that Gyre and Em can have about the earlier expeditions, and about whether Em is telling Gyre the truth. Perhaps if I had read the ebook rather than listening to the audiobook (excellently and emotionally read by Adenrele Ojo), I'd have skimmed... Psychological horror, in a science fictional setting, with just two characters: it's a bold debut, despite its flaws. I'm interested to read more by Starling.
