When you're writing or discussing a book, repeating the phrase "the author" can get a bit repetitive. There are plenty of synonyms you can use to add some variety to your language. For example, you could use "the writer," "the scribe," "the novelist," "the wordsmith," or "the storyteller." You could also try using specific terms related to the author's work or style, like "the poet," "the satirist," "the essayist," or "the memoirist." If you're looking for more formal or academic language, you might choose to use "the authorial voice," "the creator," or "the literary artist." Whatever term you choose, make sure it accurately reflects the author's work and style.
