A bestiary for the 21st Century, comprising of 26 chapters, each one focusing on an animal or being from A - Z, from 'Axolotl' to 'Zebrafish'. It is a wonderful, eclectic array of 'barely imagined beings', creatures that exist but are often so strange or unknown that they could have sprung from the pages of a medieval bestiary or Pliny's Natural History. In each chapter the author digresses with great dexterity, humour and intelligence, using each 'being' as way in to exploring our precarious relationship with the natural world, to better imagine ourselves and the world around us. The book is also a passionate celebration of wonder and beauty, and a recognition of the world's 'ghost species', the walking dead threatened by extinction.
