Dr. Aris Thalassa is the last human stationed at a deep-sea research outpost after global communications have collapsed due to a slow, creeping silence that has disabled all satellite and radio waves. The only remaining method of long-distance communication is through a network of bio-luminescent, sound-sensitive cephalopods the team has been studying. Aris must document their survival and final discoveries by sending "letters" via these creatures to a colleague's outpost across the ocean trench.
