Deborah van der Beek is an author and illustrator, though probably best known now for her abilities as a sculptor. She studied in London, Cambridge and Cardiff, and wrote and illustrated several books before concentrating on sculpture. Her sculpture is amazing: full of strong forms: bulls, and horses. Peter Davies, in an article written on Deborah van der Beek’s site, says her works: 'will surely become an enduring set of memorable images.' Her website (for which the link is below) has many examples of her work. I particularly like The Fifth Horseman. (Scroll down!)

Finding the book
Very easy to find, and usually cheap.
