Marr leaves Cornerstone owing to 'shifting focus' at division

Editor Sonny Marr is leaving Cornerstone this month owing to a “shifting focus” in the division’s commercial fiction publishing.

The Arrow fiction editor leaves on 19th April after four-and-a-half years with the company. During her time at Cornerstone, she published Sophie Cousens’ This Time Next Year and also approached pop duo Pet Shop Boys to redesign and reissue two classic backlist titles.

Recent acquisitions include a new novel by Cousens, Just Haven't Met You Yet, Poorna Bell’s debut novel In Case of Emergency and Eve Ainsworth’s Duckling. She has also been an active member of Penguin Random House’s community outreach programme and pioneered a pilot initiative with New Writing North.

Marr said: “It has been a privilege to spend the last four years in my dream job discovering new talent and playing my part in bringing those books to market. I am really sad to be leaving my authors, my friends and my colleagues, but I hope I can quickly find a new role where I can exercise the skills I have developed during my time at Cornerstone and continue to realise my ambitions.”
