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.,
