The sixteenth volume in the Aubrey/Maturin series, and Patrick O'Brian's first bestseller in the United States.

At the outset of this adventure filled with disaster and delight, Jack Aubrey and Stephen Maturin pursue an American privateer through the Great South Sea. The strange color of the ocean reminds Stephen of Homer's famous description, and portends an underwater volcanic eruption that will create a new island overnight and leave an indelible impression on the reader's imagination.
