Tracey Turner (Author) Tracey was the first commissioning editor on Scholastic's Horrible Histories series, and also worked across all their non-fiction titles. She lives in Bath with her partner and son and a big dog, and writes all sorts of funny and clever things, such as the Disgusting Dictionary and many titles for the Dead Famous series. Sarah Horne (Illustrator) Sarah grew up in Derbyshire, mainly under a snowdrift. She spent much of her childhood scampering in the nearby fields with a few goats. Then she decided to be sensible and studied Illustration at Falmouth College of Arts and gained a Masters degree at Kingston University. Sarah lives in London and specialises in funny, inky illustration and words for children's books.
