Moira Butterfield lived and travelled in lots of different locations as a child, and still thinks our world is an endlessly exciting place to explore.

She went on to study literature and become an author of children's non-fiction and fiction. She believes there are no limits to the imagination or to the wonder of our planet and so she has written about many different subjects, from ancient treasures to future worlds via pirates, kings, jungles and sea monsters.

Moira lives in Bath, Somerset, with her family. She loves to cycle, sew and sing.
