Sarena Nanua and Sasha Nanua are twin sisters living in Ontario, Canada. Born on Diwali ten minutes apart from each other, they grew up loving stories about twins and magic, and began writing books together when they were nine years old. After graduating from the English and Professional Writing programs at the University of Toronto, they published the RIA & RANI duology with HarperTeen. Their debut book for middle grade readers, Spirit Service, will release in Spring 2025 from Simon & Schuster Books for Young Readers.
