Humankind discovers intelligent life in an octopus species with its own language and culture, and sets off a high-stakes global competition to dominate the future.

Rumors begin to spread of a species of hyperintelligent, dangerous octopus that may have developed its own language and culture. Marine biologist Dr. Ha Nguyen, who has spent her life researching cephalopod intelligence, will do anything for the chance to study them.

The transnational tech corporation DIANIMA has sealed the remote Con Dao Archipelago, where the octopuses were discovered, off from the world. Dr. Nguyen joins DIANIMA’s team on the islands: a battle-scarred security agent and the world’s first android.

The octopuses hold the key to unprecedented breakthroughs in extrahuman intelligence. The stakes are high: there are vast fortunes to be made by whoever can take advantage of the octopuses’ advancements, and as Dr. Nguyen struggles to communicate with the newly discovered species, forces larger …

The Mountain in the Sea

5 stars

On the surface, this is a future sf book about discovering sentient octopuses and trying to communicate with them. But, this is no Children of Ruin or even a Feed Them Silence; it hinges less on plot and characters, and feels more about worldbuilding in service to philosophy.

I quite enjoyed this book, and the strongest part was just how tightly the book's themes and ideas intertwined through the book's different point of views and the worldbuilding. It's a not-so-far future book with sentient octopuses, overfished waters, AI boats that drive themselves in search of profit, drones driven by humans in tanks, and the first android (but one reviled by humanity). It's a book about language and communication, memory and forgetting, what it means to be human and exist in community, and about fear of others.

Nice ideas, not so nice execution

2 stars

There are some nice ideas in this sci-fi book. However, the narrative is quite clunky, characterisation of the protagonists tends to be uninteresting and/or cliché-filled, there is quite a lot of exposition of context that feels unnatural and clearly reader-directed rather than being organic to the plot.

Mind-bending, thoughtful spec-fic thriller about non-human intelligence

5 stars

Absolutely adored this book. A lonely scientist is tasked with deciphering possible signals from an apparently advanced species of octopuses on an island in the near-ish future. That's the basic plot, but the author digs into linguistics, AI, non-human intelligence, and communication generally in a gentle and well-paced thriller. Super fun read.

Asks many interesting questions, has the sense not to try to give pat answers

5 stars

So much to love about this book, how it weaves together unanswerable questions about consciousness and computation, together with a much more didactic message about humans' consumptive relationships with, well, everything including each other, and enough of a mystery story to keep the plot moving along. Also some great evocations of places (ahhh, multiple key scenes on Istanbul ferries), and of the ways peoples' reputations misrepresent their selves.

It's not a strongly character driven book - every character that is fleshed out seems to be a variant of "loner who wishes for connection" and largely a vehicle for the author's ideas - but there's enough depth to the characters to keep me reading. My one real criticism is that the ending felt a bit rushed. Not in the sort of too convenient, story-undermining way, but not quite satisfying either. It doesn't feel like a set up for a sequel, but …

many intelligences

4 stars

Impressed by how many types of intelligence and consciousness are woven together in this book. I count at least 9; some characters embody multiple kinds in ways that become clear.

One thread seemed less necessary, and another one was very grim, but worth the payoff. And this is the only cyberpunk cryptid first contact SF I can think of.

Review of 'The Mountain in the Sea' on 'Goodreads'

3 stars

This is top-notch science fiction. It is about super-intelligent cephalopods, artificial intelligence, and the fatal shortcoming of our species all at once. I would give it more stars, but the story doesn't have a destination, perhaps because it isn't fictional enough.

Thematically driven

3 stars

This is less about the characters or the plot, and more about the philosophies and science. My favorite parts were actually the fictional book excerpts between chapters, and I may need to read the books he acknowledges as helping him shape the ideas presented in the book. This strikes me as a political thriller (without the thrill part) focused on connection, communication, and choice. Which, I suppose is a way of saying the book is about consciousness. Despite how dry that might sound, I actually enjoyed the book. I finished it fairly quickly; it reads smoothly and compellingly despite (or maybe because of?) the too-even tone, in my opinion. Pacing occasionally felt bogged down by setting, and there were some spots where the dialogues were clearly an info dump vehicle, but I found the info interesting so I didn't mind too much. The plot resolution was sudden and felt abrupt, …

Amazing

5 stars

This is one of my favorite books from 2022. It investigates how difficult communications will be when the two parties have almost no common reference. It takes a swipe (perhaps not intentionally) at the books and movies where alien communication moves rapidly from no commonality to complete sentences conveying complex abstract topics. Along with language, the book also explores consciousness and what makes a person a person.

The environmental message never feels heavy handed, and while it often paints a disturbing picture, it also offers a hopeful outlook.

As I neared the end I worried that it would take a sloppy shortcut to wrap up so much, but the ending was quite satisfying, although perhaps not in the ways I was expecting.

Review of 'Mountain in the Sea' on 'Storygraph'

5 stars

This book is precisely what I yearn for in science fiction as a whole. Deeply hopeful and carefully crafted. The entire story felt like a puzzle that fit together in a precise way, all the way to the very end.
