I read this in one sitting during the October 24 hour readathon, and it was exactly what I was looking for. This is about Gyre, who has taken a job to explore a planet’s cave system. She had to lie a bit on her resume, because she doesn’t actually have the experience required for this kind of job, but she needs the money. Soon after she descends, though, she learns a few new things about this solo expedition: her handler, whose voice she hears in her suit, is the only one guiding her. Usually, there would be a whole team, but instead, she has Em. Also, many cavers before her have died in these tunnels.

Em is obsessive about this mission, and she will stop at nothing to get it done, including overriding Gyre’s suit, locking her out or injecting her with chemicals to make her sleep or make her alert. This is, of course, on top of the already existing horror of this situation. It’s a claustrophobic space, and it includes underwater caving, which is deadly in the best of circumstances. Then there’s the tunnellers: giant tunneling monsters who will hunt down any humans they can. Gyre’s suit should protect her from being detected, but she has limited supplies to keep it functional, especially when things quickly begin to go wrong.

If that wasn’t enough, Gyre begins to suspect she’s not alone down here. She thinks she sees evidence of someone without a suit surviving down here, but that’s impossible. And there’s also a non-zero chance she’s hallucinating after stumbling on some mysterious spores…

Of course, this is the Lesbrary, so it’s also queer. Gyre and Em have an… interesting relationship. She’s in the cave system for weeks, dependent on Em’s guidance to keep her safe, while also completely distrusting her. As they spend more and more time together, though, and get to know each other, Gyre finds herself reluctantly becoming attached. This is, to be clear, a toxic relationship, but wow was it compelling. Despite Em’s manipulation, I ended up rooting for the two of them, which just shows how well written their dynamic was. If you like the kind of Killing Eve dynamic in F/F relationships, you’d probably appreciate this one.

This is an engrossing blend of psychological horror and survival story. By the time Gyre realizes how deadly this mission is–all caving comes with risks, but this one has more than she was informed of–she’s unable to back out. She is always on the edge of running out of supplies, especially oxygen. As if being trapped underground wasn’t confining enough, the suit becomes claustrophobic after a while, with her desperately wanting to feel anything against her skin, to breathe air freely, or to eat naturally instead of having nutrients injected into her digestive system.

This ticked every box for me, and reading it in one sitting made me feel immersed in this unsettling story. If you’re looking for a creepy, claustrophobic, psychological horror sapphic read, I can’t recommend this highly enough.
