Irish authors Donal Ryan and Sally Rooney, and Northern Irish author Anna Burns, have been longlisted for the 2018 Man Booker Prize.

Donal Ryan is longlisted for the second time, this time for his novel 'From a Low and Quiet Sea' while Sally Rooney receives her first nomination for 'Normal People'.

Mr Ryan is from Co Tipperary and is a writer and lecturer in Creative Writing at the University of Limerick.

His first published novel ‘The Spinning Heart’ was longlisted for the Man Booker Prize in 2013 and he has since published a number of novels and a collection of short stories.

His awards include the Guardian First Book Award and an Irish Book Award.

'From a Low and Quiet Sea' moves from Syria to a small town in Ireland and tells the story of three men, one a refugee, another a young Irish man searching for his place in the world and the third an older man with a troubled past.

Speaking on RTÉ's Morning Ireland, Mr Ryan said the second time being listed is even more exciting than the first.

He said he never dreamt he would be nominated in the first place, so for it to happen twice is "pretty unbelievable".

Ms Rooney, from Mayo, published her debut novel 'Conversations with Friends' in 2017 to critical acclaim.

Her new book 'Normal People' is set in Trinity College Dublin and is due to be published in September.

She said it is "quite a surreal, strange feeling" to be nominated.

Also speaking on Morning Ireland, she said awards are "incredibly subjective" and it is always going to be a reflection, to some extent, of what is going on in the literary culture and what is going on with the particular judging panel that year and their subjective tastes and preferences.

Ms Burns' book 'Milkman' is set in Belfast and explores society and the political situation from the perspective of a teenage girl.

The longlist contains 13 books, six writers from the UK, three from the US, two from Ireland and two from Canada.

Four of the authors, including 27-year-old Ms Rooney, are under 30.

The list also contains a graphic novel for the first time – 'Sabrina' by Nick Drnaso.

Michael Ondaatje is also nominated for his seventh novel, Warlight.

It comes just weeks after he took home the Golden Man Booker for 'The English Patient' (1992), a one-off accolade to mark the literary prize's 50th anniversary.

The Man Booker prize is open to writers of any nationality, writing in English and published in the UK or Ireland.

Up until now the books had to be published by a UK publisher, but the rules were changed at the start of this year to include Irish publishers.

The shortlist will be announced in September and the winner will be announced in October.

The winning author receives £50,000 and can also expect a boost in sales.

In the week following the 2017 winner announcement, sales of ‘Lincoln in the Bardo’ by George Saunders increased by 1,227%.

Philosopher and novelist, Kwame Anthony Appiah, the chair of this year's judges, said: "Perhaps unsurprisingly, given the times, there were many dystopian fictions on our bookshelf - and many novels we found inspirational as well as disturbing.

"Some of those we have chosen for this longlist feel urgent and topical, others might have been admired and enjoyed in any year.

"All of these books - which take in slavery, ecology, missing persons, inner-city violence, young love, prisons, trauma, race - capture something about a world on the brink.

"Among their many remarkable qualities is a willingness to take risks with form. And we were struck, overall, by their disruptive power: these novels disrupted the way we thought about things we knew about, and made us think about things we didn't know about.

"Still, despite what they have in common, every one of these books is wildly distinctive.

"It's been an exhilarating journey so far and we're looking forward to reading them again. But now we'll have thousands and thousands of people reading along with us."

The rest of the judging panel is comprised of Scottish crime writer Val McDermid, cultural critic Leo Robson, writer and critic Jacqueline Rose and graphic novelist Leanne Shapton.
