Ask The Agent: Gyamfia Osei
Simon Whaley chats to Gyamfia Osei of Andrew Nurnberg Associates about writing for the middle grade and young adult market.
This piece first appeared in print in the August 2025 issue of Writing Magazine.
Gyamfia Osei’s career began as a bookseller at Waterstones before moving to Amsterdam for two years to work in international sales at a publishing company. She returned to London and joined The Good Literary Agency, where she began building a list of brilliant authors writing from middle-grade up to adult, across both fiction and non-fiction. In 2023 she moved to Andrew Nurnberg Associates where she is developing the agency’s list of children’s authors, whilst also representing a bespoke list of commercial adult fiction and narrative non-fiction. Her authors include Esra Drake, Busayo Matuluko, Melissa Quashie, Kai Spellmeier, and Kimberly Whittam.
What do you enjoy about being a literary agent?
I love how varied the role of an agent can be, where one day can take you from editing a manuscript to negotiating contract terms or brainstorming new book ideas with an author.
