This is how the new history of the Earth began, and so the time of the Ocean has come... The large anti-submarine ship "Severomorsk" is leaving on a long voyage. Something has shrouded a huge swathe of the Caribbean Sea in fog, swallowing up islands, fishermen, sailors—everything and everyone. What's inside is unknown. Two Russian combat helicopters take off into the fog. At the helm of one of the helicopters is Sergei Subbotin, with navigator Evgeniy Golitsyn nearby. And the pilots have no idea what awaits them inside the aquasphere... The book is recommended for reading by persons over 16 years of age.
