Sarah Massini has had varied careers as both designer and illustrator. After gaining a first class degree in graphic design in Manchester, she worked as a corporate designer for blue-chip clients, including the Royal Mail and Cancer Research UK. She is also the creator of Bloomsbury's iconic Diana logo. However, the pull of illustration drew Sarah inexorably into children's publishing, firstly as an art editor and now as the critically acclaimed illustrator of over 30 books. These include the best-selling The Girl And The Dinosaur and classics such as The Velveteen Rabbit and The Little Prince. The New York Times praised Sarah's art as "...fantastically stylish... gorgeous and altogether satisfying?"
