The five category winners in the 2018 Costa Book Awards were announced on Monday evening - with Sally Rooney's all-conquering Normal People securing the Best Novel gong.
Rooney, 27, becomes the youngest ever winner of a Costa Novel award. The judges said her novel - which has already won the Waterstones Book of the Year Award - was a "trailblazing novel about modern life and love that will electrify any reader". The millennial romance has an impressive 4.53 BIM rating from 15 reviews.
The Seven Deaths of Evelyn Hardcastle, Stuart Turton's witty sci-fi/mystery mashup won the award for Best Debut Novel. The Costa judges described it as an "ingenious, intriguing, original and highly original mindbender of a murder mystery".
J.O.Morgan's Cold War poem Assurances won the Poetry category award, with the judges dazzled by its "originality and inventiveness".
In the Best Biography category, The Cut Out Girl, Bart Van Es' personal exploration into how his family hid a young girl from the Nazis in Amsterdam, got a unanimous nod from the judging commitee. "The hidden gem of the year", they said.
Rounding up the Costa category award winners was Hilary McKay, whose The Skylarks' War was selected as the Best Children's Book. "As perfect a novel as you could ever want to read," said the judges - which is quite appropriate, given its BIM rating is a perfect 5 out of 5.
