Marianne grew up in Tullamore, Co. Offaly and now lives in Dublin. Along the way, she gained a first-class honours Degree in Visual Communications from the National College of Art and Design and an M Phil in Creating Writing from Trinity College Dublin. Writing poetry for her M Phil led to a period of songwriting, and a couple of her demos were played by Tom Robinson on BBC Radio 6 ‘Introducing’. Songwriting opened up her mind to the possibilities of metaphor and wordplay; over time she began experimenting with longer prose pieces, short stories, a children’s book.
Her debut novel ‘A Quiet Tide’ was published in 2020. It was shortlisted for the 2021 Kate O’Brien Award; in spring 2022 it featured on RTÉ Radio One Book on One.
Marianne is a 2024 Irish Writers Centre Evolution Programme awardee and the recipient of a 2024 Arts Council Literature Bursary.
She is currently adapting ‘A Quiet Tide’ for the screen with the assistance of Screen Ireland and working on a new novel.
