Grand Central announced the world English publication date for Ken Follett‘s next book, CIRCLE OF DAYS: September 23, 2025. As previously announced in May, the book explores Stonehenge. Follett writes, “Stonehenge is one of the world’s most iconic and recognizable monuments but, in reality, so little is known about it. How was it built? Why was it built? Who built it? I’ve written before about moments of great human achievement and I’ve always been drawn to stories of ordinary people doing seemingly impossible things, and what could be more extraordinary than the construction of this enormous monument.”
Hachette also named same of the international co-publishers who were left unspecified in the earlier May announcement, which are now incorporated into the deal record.
