Known for her sharp eye for talent, ability to nurture writers, and unrelenting commitment to storytelling, Summerhayes has carved a remarkable reputation in publishing.
Early Beginnings and Passion for Books
Cathryn Summerhayes’s career in publishing did not start by chance. Like many literary professionals, her path was rooted in a love for words and stories. She began her professional journey with Curtis Brown, one of the most established literary agencies in the UK. Starting as an intern, she was quickly recognised for her instinctive ability to spot engaging narratives and her approachable manner with writers.
Her passion for books was not limited to reading alone; it was coupled with a clear ambition to help writers bring their stories to life and place them in the right publishing hands. This combination of literary taste and business acumen set the foundation for her future success.
A Career Shaped at WME
Summerhayes moved on to work at William Morris Endeavor (WME), one of the world’s most powerful talent and literary agencies. There, she developed a reputation for managing a diverse and high-profile client list. At WME she learned how to operate within a global framework, dealing with both UK and international publishers, and navigating the increasingly interconnected world of publishing rights, film adaptations, and international sales.
Her decade-long career at WME was pivotal in strengthening her industry network, building trust with publishers, and establishing herself as a bold yet supportive representative for her clients.
