Tracey Turner (Author)
Tracey was the first commissioning editor on Scholastic's Horrible Histories series, and also worked across all their non-fiction titles.

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.
