An ocean of knowledge and wit. Frank Schätzing's captivating panorama of our estranged homeland: the seas. Over four and a half billion years of secret stories, powerful dramas, astonishing twists, and strange inventions like photosynthesis, sex, or humans. In his new book, Frank Schätzing magnificently narrates the underwater universe and how it shapes our future. Is the shark cruel for eating humans? Is humanity cruel for eating oysters? Does the shark become aware of the victim's suffering when it screams? Or does it perceive the scream as a delightful indication of the freshness of its meal, just as we benevolently regard the twitching of the oyster when we drizzle its flesh with lemon juice? By the way, this is not a plea against eating oysters. Humanity and the sea. A peculiar relationship marked by love, hate, and ignorance.
