SAllied Rooney has become the youngest author to win the Costa Novel Award, four months after she was dropped from the Booker Prize list.
The 27-year-old won the award for her older story, Normal People, described by the Costa Judges as "a bubbly novel about modern life and love that will electrify any reader".
The Irish writer was longlisted for the Man Booker award last year and tipped to win. But Normal People did not list the things that many saw as a snub for a novel that was both critically acclaimed and a commercial hit.
Her Costa Win is the last milestone in a career that began with her first novel, Conversations With Friends, written while studying for an MA at Trinity College Dublin. It was picked up by a publisher in a seven-way auction.
She has been hailed as "the first great millennium writer" and "Salinger for the Snapchat generation", and Normal People is now adapted to BBC Three with the Oscar-winning Lenny Abrahamson as director.
It's the story of a romance between Marianne and Connell, growing up in the same small town in Ireland and beginning a preliminary relationship that continues over the years.
The Costa Book Awards are divided into several categories, and the overall winner is announced on January 29.
