The Mountain in the sea

Ha is a scientist who specialises in octopus communication/consciousness/civilisation.  
She's invited to study on an island, with the only synthetic human on earth, the possibility of such octopi found. 
The other person on the island is a war veteran - who controls drones from a cage in liquid - and the drones are bilateral extentions - a bit like an octopus. 
Two other stories that we follow: a hacker hired to hack the synthetic and a slave on a fishing fish. 
The octopi are developing and there is a contact. 

It's a book that made me think about connections/networks. It has in a subtile interesting way connected this idea of thinking legs of the octopi with society, where individuals are the product of a system and yet change the system. 
A great exploration into complexity, agents and consciousness.
