She now lives in a house in North London, which she shares with her Abyssinian cat called Sushi (Susan's favourite food!) and three guinea pigs called Rembrandt, Morandi and Jackson. Susan started her career in illustration when she signed up to a training course to become a graphic designer. She quickly realised she preferred simply doing the 'picture' bit, and it didn't take long for Susan to quickly establish herself as a popular illustrator and designer.
