With stunning illustrations throughout, the book is written as a travel diary by Lazaro de Sahagun, eminent naturalist and explorer and concerns his voyage to a mysterious isle and subsequent cataloguing of the astonishing life forms, each with a unique history and mode of existence. Perhaps, as Lazaro muses, if the earth is a living organism as he believes, places like this island are necessary for the planet to safeguard these marvellous species from 'future periods of global decadence.'
