British writer Helen Dunmore, who died in June, has been posthumously awarded the 2017 Costa Book of the Year.
The poet and novelist won the prize for her final poetry collection, Inside The Wave, which she explores the borderline between the living and the dead.
The collection, which previously won the Poetry Award, was described by judges as “an astonishing set of poems - a final, great achievement".
Dunmore died of cancer in 2017, aged 64.
She is now the second writer in the award's 46-year history to win the overall prize posthumously - Ted Hughes previously won the Poetry Award and Book of the Year in 1998 for Birthday Letters.
Inside The Wave is the eighth poetry collection to take the overall prize at the Costa Book Awards and beat Gail Honeyman's Eleanor Oliphant Is Completely Fine, the bookies' favourite.
The other nominees in the running for the prize were In The Days Of Rain by Rebecca Stott, Reservoir 13 by Jon McGregor and Katherine Rundell's The Explorer.
Dunmore's son Patrick collected the prize - a cheque for £30,000 - at an awards ceremony in London on Tuesday.
"We all felt this is a modern classic; a fantastic collection, life affirming and uplifting,” Wendy Holden, chair of the final judges, said. "The poems carry powerful messages that speak to all of us."
Luan Goldie, a primary school teacher and former business journalist, won the public vote to win the Costa Short Story Award for Two Steak Bakes And Two Chelsea Buns.
