To edit a book before publishing, you need to step away from your manuscript for a few weeks to gain a fresh perspective. Start with big-picture structural and plot changes. Look for the holes in the story or weak character arcs. Then cut out scenes or subplots that do not move the core story forward. Professional editors working at a book publishing company UK suggest speaking words out loud to find clunky dialogue, awkward phrasing, and bad sentence rhythms. Then search your text for overused filler words, repetitive adverbs, and weak modifiers. Lastly, you need to fix grammar, which includes spelling and punctuation errors and formatting inconsistencies.
