Edinburgh-based Kate Atkinson is in the running for the Costa Novel Award again two years after she previously claimed the title.
It was claimed by another Scot, Ali Smith, 12 months later.
A God In Ruins, Atkinson’s time-travelling follow-up to the 2013 winner Life After Life, explores the life of RAF bomber pilot Teddy Todd.
Atkinson, the creator of private investigator Jackson Brodie, whose exploits were turned into the exploits on Edinburgh-set TV series Case Histories, had won the same prize in its previous guise as the Whitbread Novel of the Year back in 1995 with Behind The Scenes at the Museum.
Dundee-born poet Don Paterson, who is also a composer and musician, has also made the Costa Poetry Award shortlist for his 40 Sonnets collection.
He won the Whitbread Poetry Award in 2003 for his book Landing Light.
The Costa Book Awards, which date back to 1971, are only open to authors based in the UK and Ireland.
This year they attracted 638 entries across the five categories, which also include best first novel, best biography and best children’s book.
All five winners, who will be announced in January, will go on to compete for the honour of Costa Book of the Year, which comes with a £30,000 prize.
