AJ Harper

AJ Harper is a developmental editor, writing teacher, and author who has spent more than two decades helping nonfiction writers produce books that make a genuine difference for readers. She is the founder of the Top Three Book Workshop and has worked as a ghostwriter, collaborator, and editor on hundreds of nonfiction titles, including several major bestsellers. Harper’s expertise sits at the intersection of craft and reader psychology: she teaches authors to understand what their readers actually need and to structure their books around that transformation rather than around the author’s own expertise or narrative convenience. Write a Must-Read, her first solo-authored book, distills her editorial philosophy into a practical framework now widely adopted by writing coaches, book coaches, and developmental editors across North America.
