 Ní Dhomhnaill's writings focus on the rich traditions and heritage of Ireland and draw upon themes of ancient Irish folklore and mythology combined with contemporary themes of femininity, sexuality and culture.Her myth poems express an alternative reality and she speaks of her reasons for writing about myths as those that are an integral part of the Irish language and Irish culture.‘Myth is a basic, fundamental structuring of our reality, a narrative that we place on the chaos of sensation to make sense of our lives’

Ní Dhomhnaill's husband died in 2013.
