The War of 1812 continues, and Jack Aubrey sets course for Cape Horn on a mission after his own heart: intercepting a powerful American frigate outward bound to play havoc with the British whaling trade. Stephen Maturin has fish of his own to fry in the world of secret intelligence. Disaster in various guises awaits them in the Great South Sea and in the far reaches of the pacific: typhoons, castaways, shipwrecks, murder, and criminal insanity. Jack Aubrey, a brilliant and fearless captain in Nelson's navy, accepts a mission that will test his abilities to the limit: he is to set sail immediately for Cape Horn, to intercept a powerful frigate intent on wreaking havoc among British whalers. Aubrey's beloved ship, HMS Surprise, is up to the task, but many of her sailors are untried. Aubrey's confidant, ship's surgeon Stephen Maturin, has orders of his own in the world of secret intelligence. As the Surprise and her crew draw closer to the enemy, their journey grows ever more dangerous: murder, shipwreck, and a desperate rescue attempt await them in the far reaches of the Pacific.
