Taking humanity's complex relationship with the sea as its starting point, Seven Tenths is an enticing meditation on the sea as the physical birthplace of the human race and the emotional source of our dreams. Shifting effortlessly between the sciences and the humanities--between cartography and poetry, between ecology and philosophy--Hamilton-Paterson has created one of the most engrossing works on the sea in recent memory. The prose is never less than stunning, even as it is employed to describe exactly what happens to a human body during a burial at sea, as it sinks slowly through miles of water.

At a time of growing concern about our degradation of the oceans, this extraordinary book is an immensely relevant and powerful reminder of the power, fragility and sublime beauty of the sea.
