Sarah Brennan is the author of the best-selling Chinese Calendar Tales, the Dirty Story series and the multi-award-listed Storm Whale, all for primary school-aged children. Born in Tasmania, Australia, she grew up on the slopes of Mount Wellington surrounded by bush animals, goats and exotic poultry. She also played the bagpipes (at the very bottom of the garden) and wrote lots of stories and poems which she kept in a big pink plastic bag. Sarah worked in London before moving to Hong Kong, when she showed her plastic bag to a publisher and her first book was born. Sarah has a French husband and two grown-up daughters, and divides her time between France, Hong Kong and Australia, touring schools all around the world virtually and in person.

Charly Cheung is an award-winning illustrator. She started doodling on scraps when she was three years old and her bedroom walls were always filled with finished jigsaw puzzles, the largest being over 2000 pieces! She has loved puzzles ever since and spends a lot of her time solving logic games. She also loves picking out the tiniest details other people cannot see, such as little caterpillars and tiny bits of fluff which her Maltese dog leaves around the house. She was born in Toronto, Canada, grew up in Hong Kong, then studied in London, where she illustrated her first children’s book for Real Reads’ William Shakespeare series. She has won or been short-listed for prestigious awards including the World Illustration Awards, Applied Arts Cartoon/Comic Illustration Series and American Illustration. She lives in Hong Kong.
