Irvine Welsh and James Kelman are among the famous names in the running for the Saltire Literary Awards.
Welsh's The Blade Artist, featuring the return of Trainspotting character Begbie, has been shortlisted for the Fiction Book of the Year award.
He is up against Kelman's latest novel Dirt Road, as well as the Man Booker Prize-nominated His Bloody Project by Graeme Macrae Burnet.
Also shortlisted are The Sunlight Pilgrims by Granta best young British novelist Jenni Fagan, Kevin MacNeil's The Brilliant & Forever, and This Must Be The Place from best-selling author Maggie O'Farrell.
The Saltire Society organises the awards, which cover poetry, research, non-fiction, history and first-time writers. Winners are given £2,000.
Kathleen Jamie and Don Paterson are among those shortlisted for the Poetry Book of the Year award, while Orkney author Amy Liptrot's The Outrun and John Kay's Other People's Money are two of the candidates for the non-fiction award.
Those in line for the First Book of the Year award include Scottish lawyer Isabel Buchanan for her biographical account of working on death-row cases in Pakistan, aged 23.
The shortlists were revealed at an event in Edinburgh on Thursday and the winners will be announced next month.
The winning book from each category will go on to compete for the Saltire Scottish Book of the Year award and a £6,000 prize, which last year went to Michel Faber for his novel The Book of Strange New Things.
Jim Tough, Saltire Society executive director, said: "Spanning academia, poetry, biography and prose, the sheer scale and variety of writing talent to be seen in the shortlists is remarkable.
"As always, excellence is evident across all awards and I know the judges will have their work cut out to decide upon winners."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
