A tight first-person recollection of an expedition to the now uninhabitable tropical regions of the planet... and what is found there
Doctor Jasmine Marks is a solution to a problem. A couple of decades ago, she was on an expedition to The Hygrometric Dehabitation Region, the “Zone,” a growing band of rainforest on the equator. The Zone is way too hot, long-term uninhabitable to humans, but if one could... its economic potential could be invaluable. And so Marks is recruited for another mission to the Zone. Another mission to try and complete the goals of the first mission, and a chance to find her lost mentor, Doctor Fell.
This is the story of Saturation Point by Adrian Tchaikovsky.
Tchaikovsky’s near-future world, his worldbuilding, plot and narrative twists, rely on the concept of “wet bulb” temperature. That is to say, high temperature, high humidity environments, extreme by even modern standards. You see, even in a desert at extreme temperatures, the human body can sweat, and try and cool itself, and hydration can stave off and make life possible, or at least plausible in hot and dry conditions. But in hot and humid conditions, when the wet bulb temperature, as it is called, is too high, the human body cannot sweat to cool itself. No mammal can, in fact. And so the body temperature rises, proteins denature, and death occurs. Thus a spreading zone of tropical heat, hot and wet, is a death zone for humans and most forms of life. In a world where climate change has ravaged inhabitable land, trying to make a go of the Zone would be of enormous economic benefit. Or at least to a megacorporation or two, anyway.
And thus, two decades after her previous trip, Dr. Marks is recruited by a corporation to go back in the Zone with a team, acting as the “native guide” due to her previous experience. They are suited, kitted and seemingly ready to tackle the dangers of the Zone. The cover story they give Marks and the others is a plane crash inside the tropics, a chance to save the survivors. It’s a lie, of course. But by the time Marks and company are told the truth, it is far too late and they are committed to the project and deep within the Zone.
It does not go well.
The story is told in a series of first-person debriefing sessions of Dr. Marks after the expedition. This narrative structure gives Tchaikovsky a lot of room to play with form and hold and withhold information. Marks’s may be a reliable narrator and tell us what she sees and experiences in a given moment, but the strength of a first-person point of view is that things can and do happen outside of that camera lens. Also, since it is in a debriefing format, this gives Marks the opportunity to curate and shape her answers, experiences and recollections, which Tchaikovsky makes great use of as well to make this a careful narrative experience.
There is one more aspect to this, one I didn’t catch at first, but as the narrative went on, I noticed it more and more. The session debriefings are not all there. We hop, skip and jump across numbers. We get a necessarily narrowed and limited set of recollections of the expedition, and the author makes ever greater use of those blank narrative spaces to help shape the story. It’s something that comes into focus and best appreciation once the story is done (this is a story for writers and fans interested in the craft to read and then reread to look at *structure*). I have noticed that shorter forms by the author are where he likes to play with narrative devices and forms and ideas like this in various ways, compared to the more traditional form of many of his bigger novels. While those bigger novels are bigger canvases and I would not trade those for the world, these shorter works are refreshing and interesting.
In a tight novella format with that point of view, we get a curated experience of worldbuilding. Tchaikovsky moves briskly, moving Marks to the Zone in short order, but not before we get a sense of his megacorporation-dominated near-to-medium-future world. And again, like with the use of sessions and the like, what he doesnt’t say and doesn’t mention weighs as heavily as the details we do get. Things flip on their head when we are in the lushness of the Zone and we get the riot of life and its alien-planet-like conditions. This is Tchaikovsky in his main element, and the Zone would be a terrifying and dangerous place even if there weren’t dangerous animal life... or on the other hand, if the wet bulb temperatures weren’t deadly to humans. Together, it makes for an experience of waiting for the dominoes to fall. We know Marks must survive... but everyone else is fair game.
We get thumbnail sketches of all the characters, just enough to know them and care about them as they face the horrors of the Zone. This human factor really is the secret sauce that lifts the author’s work an extra notch. The alien ecology of the jungle environment is a keeper, but add the characters, and I found myself impatient to get back to the book to listen to the next “session” from Dr. Marks as her journey progresses, to find out what happened next, and who might be the next to fall to the dangers of the Zone.
I listened to this book in audio. This is not the first book I’ve listened to by Adrian Tchaikovsky that has been narrated by Emma Newman (she seems to like narrating books by Tchaikovsky with female protagonists). Newman brings the passion, sometimes desperation that Jasmine Marks shows in her session entries. And as the secrets of the narrative reveal, Newman helps sell the narrative with her vocal talents.
With Saturation Point, Tchaikovsky’s interests in strange alien ecologies and the interface between them and the human factor wind up in a winning narrative combination. The short novella format, with the session structure, is sharp, punchy and hits the line between not being too short and not being overlong either. This is the sort of novella that you don’t wish was really a novel, especially given the ending. It’s a fascinating and engaging world, but this narrative is quite well contained.
In a thematic and artistic sense, Saturation Point feels like a first cousin to Tchaikovsky’s Alien Clay. While there are connections to be had through all of his work, the resonances of these two books make them feel like a package deal, and if you liked one, I can heartily recommend the other to you to complete the pair of definitive 2024 SF experiences from Tchaikovsky.
Highlights:
- Engaging audio version narrated by Emma Newman
- Strong use of point of view
- Future tropics Earth as deadly alien landscape
- Cover art gives clues as to what Marks and her team find in the Zone
