Jacqueline Sinclair

Editor and writer specializing in story consultation, manuscript critique, and developmental editing for novels and narrative nonfiction.

Jacqueline Sinclair studied law, then traded courtrooms for passports, living in South Africa, London, and Hong Kong before settling in Los Angeles.

Drawn to deeper character, she specializes in editing, ghostwriting, and story consulting—work she’s done for over 15 years. She joined The Editorial Department in 2011, where she works on novels and narrative nonfiction. She also recently published a spicy romance series under a pen name. Her reading tastes vary widely but gravitate toward imaginative works in any genre with well-defined characters, memorable plotlines, and fascinating settings.

Jacqueline brings a warm, focused approach to editing, always keeping an eye on what a manuscript needs to succeed both creatively and commercially. She’s especially sharp on structure, pacing, POV, character, dialogue and fast-moving plots.

She’s a great fit for authors seeking an editor who understands story from the inside out, whether the draft is polished or still in progress. She often uses outlines to help clients clarify structure and sharpen their work.

Jacqueline’s favorite authors include Angie Thomas, Gillian Flynn, Margaret Atwood, Ken Follett, Hannah Rothschild, and Arthur Golden.
