Helen Dunmore has won the Costa Book of the Year prize for her 10th and final poetry collection, Inside the Wave.
The Costa awards including the prize for poetry, which she won earlier this month, recognise authors based in the UK and Ireland.
Dunmore died from cancer in June 2017 at the age of 64.
The overall winner is chosen from five books which had already won prizes in the categories of novel, first novel, biography, poetry and children’s book.
The ceremony, previously known as the Whitbread Book Awards, has taken place annually since 1971.
The other winners of the Costa category prizes were:
