Sally Rooney's second book The People's and Donal Ryan's Poor and Poetry Sea have been shortlisted for the Costa Novel Award, considered the most prestigious award for a novel open to British and Irish writers.
Rooney, from Mayo, and Tipperary-born Ryan, were both longlisted for this year's Man Booker Prize which was won by Belfast author Anna Burns for Milkman. Rooney was also named International Author of the Year at Britain's Specsavers National Book Awards and all three Irish authors were shortlisted for Novel of the Year at next Tuesday's An Irish Book Awards.
The Costa riders described Rooney's novel as "bold, fresh and intensely modern" and Ryan's as "compassionate, profound and masterfully written".
Director Lenny Abrahamson is planning to make a TV adaptation of Normal People.
Also on the shortlist is 70-year-old Anne Youngson, from Oxford, for her debut novel, Meet Me At The Museum.
The Costa Prize has five categories: Novel, First Novel, Poetry, Children's Book and Biography. Each category winner receives £ 5,000 while the overall winner of the 2018 Costa Book of the Year, will receive £ 30,000.
Previous Irish winners include Sebastian Barry, Jennifer Johnston, and William Trevor, who won twice.
