Astrid Foss is very secretive. We're not sure where she lives or even if that's her real name... We imagine that she takes her huskies for a walk every morning, then heads back to her log cabin where she sits with a hot chocolate and dreams up icy adventures. She loves ginger biscuits and knitting complicated hats.

Monique Dong studied to become an animator, but soon realised she had a love for illustrating children's books and has been following that dream ever since. Born in South Africa, she now lives in China with her husband and baby boy.
