The length of The Castle Cross the Magnet Carter caused several publishers to pass on the novel or suggest that it either receive major cuts or be broken into a trilogy; Corthron persisted until Seven Stories Press finally accepted the manuscript in September 2014. The original editor of the book at Seven Stories had resisted its publication, and Corthron believes the advocacy of another Seven Stories author, who brought the book to the primary editor at Seven Stories, was critical to its eventual publication. Corthron would cut 400 pages of the 1,200-page manuscript for final publication.
