Milly Reilly – Editor

Literary agent at Colwill & Peddle, editing and representing a dynamic list of authors of fiction and non-fiction.

Overview

I’m a literary agent at Colwill & Peddle, where I represent fiction and a broad range of non-fiction spanning memoir, narrative non-fiction, essays, creative non-fiction and cookery. Authors I represent include Dr Annabel Sowemimo, Jacqueline Roy, Alexina Anatole, Gabrielle de la Puente and Zarina Muhammad.

Before joining Colwill & Peddle, I worked for over six years at Jo Unwin Literary Agency, where I worked alongside Jo with authors such as Kit de Waal, Candice Carty-Williams, Brian Bilston and Georgia Pritchett.

I am a hands-on editor, and I love working closely with writers to consider the different, generative ways of telling a story or developing an idea or argument within their writing. I enjoy working on the big and small of a text, from energising and honing shape and structure to fine-tuning on a sentence level. In fiction, I’m particularly interested in character-driven stories, and in non-fiction I’m drawn to innovative, critical thinking and expert voices.

I offer developmental editing, editorial assessment, query letter review, copy editing and proofreading. Across my editorial work, I strive to deliver a combination of careful thought, imagination and approachability. Please do get in touch – I'd love to talk more.

Milly has done a really excellent job editing my query letter and synopsis, making them both more readable, relevant and the correct length for submitting to agents. I have already had a request to send my manuscript to an agent!
