THE NEW GIRL - Hodder (UK) and Random House (US) - 9th July 2020

She's borrowed your life. What if she decides to keep it?

Glamorous Margot Jones is the fashion editor at glossy women's magazine Haute, and pregnant with her first child. Margot's used to her carefully curated life being the object of other women's envy - who wouldn't want her successful career, loving husband, beautiful house and stylish wardrobe?

Maggie, a freelance journalist, certainly knows she doesn't measure up. So when Margot gets in touch to suggest she apply for her maternity cover at Haute, Maggie seizes the chance at living a better life - even if it's only temporary.

But the simultaneous arrival of Margot's baby and a brutal end to her oldest friendship sends Margot into a spiral of suspicion and paranoia. Are Maggie's motives as innocent as they seem? And what happens at the end of the year when Margot wants her old life back - especially if Maggie decides she doesn't want to leave?

‘I was so absorbed by The New Girl. In this suspenseful debut, Harriet Walker applies the finest of brushes to those shades of grey between friendship and rivalry – not so much domestic noir as domestic gris. I recommend.’ - Louise Candlish

'"With elegant prose and complex, vivid characters, THE NEW GIRL is a delicious slow burn of a thriller. I can't wait to read more from Harriet Walker" - Andrea Bartz, author of The Herd and The Lost Night 

"[She] movingly portrays the fragility of friendship and the corrosive effect of mistrust and recriminations in a wickedly funny psychological thriller that’s in turn brutal and tender. Walker is off to a fine start." - Publisher's Weekly 

"Fusing society’s heavy reliance on social media with a plot that is both pacy and rich with tension and a cast of unreliable and flawed characters, The New Girl is suspenseful and stylish writing at its very best." - The Literary Edit

"Single White Female meets The Devil Wears Prada, this is an ingenious thriller that I couldn't put down. A beautifully written, tense and chilling story of toxic friendships, insecurities and guilt. This deserves to be huge." - Claire Douglas

'The New Girl does what the very best psychological thrillers do: takes a scenario that many of us know well and twists it so that it becomes utterly terrifying. Choosing a maternity leave rivalry as a plot device was a masterful stroke and it’s executed perfectly; the writing is beautiful and the storyline constantly refuses to head where you think it is going. I flew through this book in a few days (or should that be nights that were later than they were meant to be, as I read ‘just one more chapter’…)' - Caroline Corcoran
