I started writing my fantasy novel, Audrey of Farmerton, in the third person and the present tense. Because the story is told from a single viewpoint, I could have written it in the first person, but I decided against it. That was partly because the planned sequel would have multiple viewpoint characters, and partly because I wasn’t comfortable writing as though I were a teenage girl.
Why did I change from writing in the present tense to the past tense? That’s complicated. First let me give some examples.
Present tense: He is writing a blog post.
Past tense: He wrote a blog post.
Past perfect tense: He had written a blog post.
The present tense provides more of a sense of immediacy–“She opens the door and leaves in a huff.” as opposed to “She opened the door and left in a huff.” Present tense can work well, especially when there is a great deal of action. It also has the advantage that referring to earlier events can be accomplished by simply employing the past tense. On the other hand, the majority of fiction is written in the past tense. That is what is traditional, and that is what I decided I should employ.
The past tense is easy to write in, with one major exception. Referring to earlier events (outside of dialog) requires the use of the past perfect tense. This involves a great deal of “had” and “been”, and maybe even the dreaded “had had”. This is something that I am still coming to terms with. One way to reduce this nuisance is to use past perfect in the first sentence of a paragraph and then switch to past tense, possibly returning to the past perfect at the end of the paragraph to make things clear to the reader. Writing every single sentence in past perfect may be grammatically correct, but it can be tedious to read.
