Subtitled, "The Heroic Life Of The Atlantic Salmon". Part memoir part science book, this explores both the extraordinary life of the salmon and Shelton's lifelong passion for the sea. For centuries, mankind has been fascinated by the salmon: how it can survive in both fresh and saltwater, how it can navigate the thousands of miles between feeding and breeding grounds... Shelton looks at the world from the salmon's point of view to try and find out, and places the fish in its evolutionary context.
