'I loved this novel's brain and heart, its hidden traps, sheer propulsion, ingenious world-building and the purity of its commitment to luminous ideas'DAVID MITCHELL, AUTHOR OF CLOUD ATLAS'A first-rate speculative thriller, by turns fascinating, brutal, powerful, and redemptive'JEFF VANDERMEER, AUTHOR OF ANNIHILATIONThere's something in the water of Con Dao. To the locals, a monster. To the corporate owners of the island, an opportunity. To the team of three sent to study and protect, a revelation. Their minds are unlike ours. Their bodies are malleable, transformable, shifting. They can communicate. And they want us to leave.When pioneering marine biologist Dr. Ha Nguyen is offered the chance to travel to the remote Con Dao Archipelago to investigate a highly intelligent, dangerous octopus species, she doesn't pause long enough to look at the fine print. DIANIMA- a transnational tech corporation best known for its groundbreaking work in artificial intelligence - has purchased the islands, evacuated their population and sealed the archipelago off from the world so that Nguyen can focus on her research.But the stakes are high: the octopuses hold the key to unprecedented breakthroughs in extrahuman intelligence and there are vast fortunes to be made by whoever can take advantage of their advancements. And as Dr. Nguyen struggles to communicate with the newly discovered species, forces larger than DIANIMA close in to seize the octopuses for themselves.But no one has yet asked the octopuses what they think. And what they might do about it.
