That’s according to figures published by Nielsen Bookscan, as the Castlebar native’s Normal People has jumped to the number one spot in the best-sellers list in the UK and Ireland two years after the book was first published – thanks to the massive popularity of the TV adaptation of the novel.

Figures released by Nielsen Bookscan show that Rooney’s two novels have enjoyed sales generating £6.18m (€6.97m) in the UK and €1.4m in Ireland.

The figures show that Ms Rooney’s Normal People has generated sales revenues of £4.38m (€4.92m) in the UK and €1m in Ireland.

NPD Bookscan also confirm that Normal People has sold 184,000 copies to date in the US, taking the overall total of Rooney’s book sales in the US to 305,000.

Ms Rooney (29) will also have profited from the adaptation rights of her two novels to the small screen.

The Element Pictures team that produced Normal People is already working on producing Conversations with Friends.

On the impact of the TV series, a spokesperson for RTÉ said: “We a only halfway through the hit series and Normal People is already setting records on RTÉ and worldwide.”
