The debut novel from a former librarian has scooped the top prize at the British Book Industry Awards.
Andrew Michael Hurley's The Loney beat off stiff competition from literary heavyweights and commercial blockbusters including Go Set A Watchman by Harper Lee and The Girl On The Train by Paula Hawkins to be crowned Book of the Year.
The Gothic horror tale, described by Stephen King as "an amazing piece of fiction'', has already won the Costa First Novel Award.
The revamped 2016 awards saw prizes handed out in four new categories - Debut Fiction, Children's, Fiction and Non-fiction, as well as the overall Book of the Year prize.
The Loney, published by Hodder & Stoughton imprint John Murray, won the Debut Fiction prize and was also the overall Book of the Year winner.
The novel has been hailed as a true British success story, with Hurley working part-time for several years to be able to write it.
Children's Book of the Year was won by David Solomons' My Brother Is A Superhero.
It triumphed over some of the biggest names in children's publishing including JK Rowling, Judith Kerr and David Walliams.
A Little Life by Hanya Yanagihara won the Fiction category and the Non-fiction prize went to Norwegian Wood by Lars Mitting and Robert Ferguson.
The British Book Industry Awards are produced by The Bookseller magazine.
Cathy Rentzenbrink, Chair of Judges, Books of the Year and Contributing Editor, The Bookseller, said: "It's been a fascinating process to consider so many brilliantly published books and think about what it is that makes a book catch fire. All our judging meetings were lively and opinionated as we looked at the stories behind the stories.
"From A Little Life, Norwegian Wood and My Brother Is A Superhero to overall winner The Loney, these books tell an important story about British publishing - that originality and individuality really count."
