The Volunteer by Jack Fairweather has been named the 2019 Costa Book of the Year.
The news was announced on Tuesday evening at the Costa Book Awards ceremony held at Quaglino's in central London, England.
The biography by former war reporter Fairweather had already won the Costa Biography Award earlier this month.
The book is a landmark account of an unsung hero of the second World War, Polish underground operative Witold Pilecki, who infiltrated Auschwitz.
Sian Williams, chair of the judging panel, said: “The judges were unanimous in choosing The Volunteer by Jack Fairweather. It’s an incredible story; pacy like a thriller, it reads like fiction and yet it’s not, it is fact. It is a story none of us have read before – this is an extraordinary and important book that people need to read.”
Other members of the final judging panel included novelist John Boyne and broadcaster Anneka Rice.
The Volunteer beat Middle England, by novelist Jonathan Coe; The Confessions of Frannie Langton, by debut author and former lawyer Sara Collins; Flèche, the debut collection from Hong-Kong-born poet and lecturer Mary Jean Chan, and Asha & the Spirit Bird by children's writer Jasbinder Bilan to win the overall prize of £30,000 (about €35,400) at the ceremony.
Those latter four books were the 2019 winners of the Costa Novel Award, the Costa First Novel Award, the Costa Poetry Award, and the Costa Children’s Book Award respectively.
The Costa Book Awards are the only major UK book awards open solely to authors resident in Britain and Ireland.
Also announced at the ceremony on Tuesday evening was the winner of the Costa Short Story Award. Anna Dempsey, a writer and teacher, won the public vote for the prize and £3,500 for her story The Dedicated Dancers of The Greater Oaks Retirement Community.
The 2018 Costa Book of the Year was The Cut Out Girl by Prof Bart van Es of the University of Oxford. Like The Volunteer, its subject is the Holocaust.
