The Mountain In The Sea

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. She will be the only scientist to have access to these octopuses who just may hold the key to extrahuman intelligence.

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 attempt to understand the octopuses' sophisticated communications. But she may not have much time. Forces larger and more powerful than DIANIMA want access to the octopuses and are ruthless and innovative in their pursuit.

And meanwhile of course the octopuses themselves may have something to say about it...
