How to keep one voice across a whole book

The hardest technical task in a long book is sounding like one person the whole way through.

A short piece can ride on a single burst of energy. A book cannot. It is tens of thousands of words written across months, in different moods, and the reader feels it at once if the person on the page keeps changing. Holding one voice from the first chapter to the last is what makes a book feel finished. Here is how to do it on purpose.

Decide how you sound, early

Voice is made of small, repeatable choices, how long your sentences run, whether you use contractions, the words you reach for and the ones you would never use, how close you sit to the reader. Decide these early, before the draft hardens, even if only roughly. A voice you have named is a voice you can keep, because you know what you are aiming at.

Keep a touchstone

Write one page you are happy with, a page that sounds exactly like the book should, and keep it where you can see it. When you are not sure whether a passage belongs, read it next to the touchstone. The mismatch is usually obvious the moment the two sit side by side. Professionals do this with a style sheet, and you can do it with a single good page.

Expect drift, and edit for it

Voice rarely breaks in one place. It drifts, a little colder here, a little chattier there, especially where you wrote tired or months apart. You will not catch most of it while drafting, and that is fine. Catch it in a pass of its own, reading for voice alone, with the touchstone open, smoothing the joins between chapters written far apart.

Read it aloud

The ear catches what the eye slides over. Read your chapters aloud, or have your computer read them to you, and the false notes announce themselves, the sentence that is suddenly too formal, the joke that is not yours, the rhythm that stumbles. If it sounds like you when spoken, it will read like you on the page.

When the voice is not yours to invent

In memoir and family history, the voice is the real way you or your subject speaks, more than any style you pick, and the closer the book sits to that, the truer it reads. If you are writing someone else's story, listen to their recordings and keep their actual phrases, the turns only they use. The aim is a book that sounds like the person, on the page, to anyone who knows them.
