Lily grew up in the wilds of snowy nowhere, spending much of her time talking to animals and making up stories. She has continued to do this in her adult life, and now writes fiction and non-fiction books for children. Her titles include Dinosaurium, Beneath the Waves and Five Little Chicks.

Sarah studied Illustration at Kingston University and in 2011 was selected as an It's Nice That Graduate. Notably, in 2018, she was commissioned to create a series of illustrations for London Natural History Museum's 2018 Whales exhibition. She trained herself to draw animals from nature documentaries. Her unique ability to capture a creature's characteristics or the forces of nature in just a few swoops of ink is incomparable and truly impressive. Sarah's book Sometimes I Feel... won the ALCS Educational Writers' Award in 2021. Sarah lives in Hastings, UK.
