Marve has been writing for over a decade, and her trade debut fantasy novel, Firstborn of the Sun, the first in a trilogy, was published by Penguin Michael Joseph in October 2025. The novel also earned her finalist placements in several competitions, including the 2023 Future Worlds Prize.
Her debut sequel, Heir of the Shadow, will be released in fall 2026.
Marve is also an award-winning filmmaker. When she is not weaving fantastical tales, she can be found embracing life as a serial hobbyist, obsessing over myths and histories, collecting books and carefully curating her personal library, or indulging her unapologetic love of all things Christmas. She is represented by Ciara Finan and Flo Sandelson at Curtis Brown Literary Agency in the UK and United Talent Agency in the USA. She can be found online @justmarvewrites and justmarve.org
