Born in Suffolk, Sarah Ridley lives on the Suffolk/Essex border and is a writer and editor of educational books for children and young people. Recently, a life-long interest in history has led her to write books about the First World War, inspired by reading letters written by soldiers who served in the conflict. Brothers at War tells the story of uncovering the material held in her own family's archives. Dear Jelly sets letters written by soldier brothers to their younger sisters at its core. Teenage children keep Sarah busy when she isn't tied to her computer, and she relaxes by walking along river estuaries close to her home.
