Brian O'Sullivan was born in county Cork, Ireland. On completing a degree at University College Cork, he went on to travel extensively. He is now based in New Zealand with his family but returns to Ireland on a regular basis.

Brian writes fiction that incorporates strong elements of Irish culture, language, history and mythology. These include literary short stories (The Irish Muse collection), mystery thrillers (The Beara Trilogy) and contemporary versions of the Fionn mac Cumhaill/ Fenian legends (The Fionn mac Cumhaill Series and the Irish Woman Warrior Series).

Although he writes predominantly for an Irish audience, Brian's unique style and humour has meant that his books have become firm favorites of readers all around the world.

Quotes by Brian O'Sullivan (?)

“In the age of the internet, where anyone can publish unsubstantiated opinions and articles that receive no peer review, cultural misinterpretation and misinformation on Celtic cultures continues to flourish.”

Brian’s Quotes

“Pause you who read this, and think for a moment of the long chain of iron or gold, of thorns or flowers, that would never have bound you, but for the formation of the first link on one memorable day.”
― Charles Dickens, Great Expectations
