Christiane Dorion's passion for writing children's books stems from the thousands of questions she asked as a child, many of which remained unanswered: How big is the universe? When did life begin? Originally from Canada, she moved to the United Kingdom to get a Ph.D. in environmental education before working for World Wildlife Federation, United Kingdom, and later becoming an educational consultant. Her award-winning books are intended to inspire children to explore the complex systems of the world we live in and help protect it. Christiane Dorion lives in Surrey, U.K. Harry Tennant is London-born, but escaped to the coves of Cornwall to study illustration at University College Falmouth before returning to the capital of the United Kingdom once more. He now works as a freelance illustrator, using a mixture of hand-drawn and digital media to create his illustrations, and primarily produces artwork for magazines and book covers.

Harry Tennant lives and works in Hackney, U.K.
