Seashells have been the most coveted and collected of nature’s creations for thousands of years. They were money before coins, jewellery before gems, art before canvas.

In The Sound of the Sea, Cynthia Barnett blends cultural history and environmental science to trace our long love affair with seashells and the hidden lives of the mollusks that make them. From the mysterious glow of giant clams to the surprising origin of Shell Oil as a family business importing exotic shells, the book is filled with unforgettable stories. As it explores the perfect symmetry of a Chambered Nautilus, the pink-glossed lip of a Queen Conch or what we hear when we hold a shell to the ear, it makes a powerful argument for listening to shells—and acting on what they are telling us about the impacts of climate change on the seas, marine life and humanity.
