Katie has been writing non-fiction children's books for almost half her life and loves questioning the world from a child's point of view. She's developed some of Usborne's bestselling series, including the See Inside books and Lift-the-flap Questions & Answers.

When she's not writing, she likes drinking coffee, walking on the moors and playing competitive board games with her children.,

Christine was born a little before midnight on New Year's Eve in 1984. She has always loved books and as a child could be found trying her best to draw just like Beatrix Potter.

She went on to study Illustration for Children's Publishing at the North East Wales School of Art and has been illustrating since she left in 2006. Christine has created illustrations for children's books, cards, toys and clothing with companies based in the UK, US, France and Australia.

She lives and works in a Post Office in the Peak District with her partner Ste and Yorkshire terrier, Suzie.
