Available for the first time in three separate volumes, To the Edge of the World is a seafaring adventure in the tradition of Patrick O'Brian, chartering the lives of Captain Robert Fitz Roy and Charles Darwin, their friendship, and the historical voyage that ultimately drove them apart. In 1831, FitzRoy and Darwin - a Christian Tory and a liberal naturalist - board the HMS Beagle and set sail for Tierra del Fuego. As they travel around the world, exploring the coasts of Patagonia and surveying the Galápagos Islands, the two men forge a lifelong bond while debating morality, nationality, biology, fate, and religion. And as Darwin formulates his theory of evolution, their friendship is fast overshadowed by their differences as Darwin destroys everything FitzRoy stands for.
