GIRL A by Abigail Dean has sold more than 350,000 copies across all formats

Published in hardback by HarperCollins in January last year, Girl A became an instant Sunday Times and New York Times bestseller, also topping the charts in Ireland and Australia. It spent six weeks in the hardback top ten followed by 15 weeks in the paperback top ten, and the paperback was the third biggest selling of the year, reaching #1 in the UK Kindle charts too.

The novel has been acquired in 36 territories, and television/film rights have sold to Sony, with Johan Renck, director of Chernobyl, attached to work on the television adaptation.

With early endorsements from Richard Osman, Jessie Burton, and Marian Keyes, Girl A went on to be named "the year’s best debut" by The Times and to be a Waterstones Thriller of the Month in paperback. The paperback TCM has now passed the 144,000 mark to date.

Abigail Dean was named an Observer New Voice in January 2021; now, in January 2022, she is one of ten writers to be shortlisted by Good Housekeeping and the Women’s Prize for Fiction for "Futures 10", which aims to highlight the next generation of female authors.

Her second novel, Day One, is scheduled to publish in January 2023. Set in the aftermath of a brutal school shooting in a quiet lakeside town in the North of England, Day One is a tender, heart-breaking novel about community, tragedy, and the lasting power of love.'

Phoebe Morgan, Editorial Director at HarperFiction, said: "It’s been such a huge honour to publish Girl A, a book myself and the HarperFiction team believed in wholeheartedly at every stage. To see Abigail’s prose resonate with so many thousands of readers is wonderful; she deserves every success and I’m so proud of everything this remarkable novel has achieved. Thank you to all the booksellers and readers who have championed Girl A alongside us and helped tell Lex Gracie’s story. And get ready for Day One!"

Dean said: "Writing Girl A, I was hoping my parents and a few friends would read it. It’s a cliche, of course, but publication really has been a dream come true. Having readers love and detest my characters – as I’ve done with those of so many other authors – has been the greatest joy."

Juliet Mushens said: "I’m so thrilled to see readers take Lex to their heart the way I did – I’m looking forward to Day One publishing and reaching an even wider audience."
