Susan Cahill grew up by the sea in West Cork, Ireland. She has lived in the deserts of Saudi Arabia and the frozen winterland of Canada, and now calls London her home.

Obsessed with stories from a young age, Susan decided to study them in university, although secretly she always wanted to be a novelist. Becoming an Associate Professor of Literature instead, Susan taught in universities until she couldn’t ignore her own stories clamouring to be told.

Susan’s debut MG fantasy thriller "The World Between the Rain" was published in 2024.
