Marian has worldwide significance and acclaim; on The Tommy Tiernan Show, she divulged that her books do particularly well in the UK, Sweden, Spain, Brazil, Australia, New Zealand, Canada and South Africa.
But despite being a renowned novelist, Marian is not just a one-trick pony.
She is also a fantastic non-fiction writer, with two collections of journalism under her belt, entitled Under the Duvet and Further Under the Duvet.
She combined these two to form Under the Duvet: Deluxe Edition, and donated all royalties from Irish sales to the Simon Community, a charity which works with the homeless.
