This year's €100,000 International Dublin Literary Award has been won by 33-year-old US author Emily Ruskovich for her debut novel, Idaho.
The winning novel was chosen from a total of 141 titles, nominated by libraries in 115 cities across 41 countries.
It was first published by Chatto & Windus in the UK and by Random House in the USA.
Ms Ruskovich is the fourth American author to win the prize in its 24-year history.
The award is the world's largest prize for a single novel published in English.
Commenting on her win, Ms Ruskovich said: "I cannot express how grateful I am to be the recipient of this astonishingly generous award. It is difficult to know how to respond to the magnitude of this kindness that has been so suddenly bestowed upon me.
"I feel shocked. I feel humbled. I feel overwhelmed with the enormity of my gratitude. I am especially honoured because of the admiration that I feel for the other finalists, authors from all over the world who are all doing such crucial and beautiful work.
"Seeing my name beside theirs when the shortlist was announced that alone was one of the greatest honours of my career."
Idaho was nominated by the public library in Brugge, Belgium and was chosen from a shortlist of ten novels from France, Ireland, Pakistan, the UK and the USA.
