Teresa Heapy (Author) Teresa swapped the office desk for the kitchen table in 2009, having worked as a Commissioning Editor for Oxford University Press for several years and deciding that what she really wanted to do was write books. Since then, she has written about gorillas, Batman, the ugly duckling and green goo (not all in the same book) for Raintree, Pearson, OUP and HarperCollins. In her spare time, she does comedy improvisation and plays the ukulele. She lives in Oxford, England, with her husband and three children. www.teresaheapy.co.uk Sue Heap (Illustrator) Sue Heap is a children's picture book illustrator and story writer.
