One of the great things about editing books is the variety of stories that are told. In fiction, I’ve edited westerns, horror, romance, suspense, chick lit--just about any genre you can come up—or maybe even a brand new one. And the same applies to nonfiction: detail-intensive analyses of politics or a cultural era, biographies of the famous and not so famous, and all kinds of personal memoirs, whether about a single life or a personal overview of a time and place.
As an example, I just recently completed the initial edit of a truly suspenseful novel with a juicy romance intertwined with it—a good combination, and an opportunity to heighten the impact of each plot with the color and detail from the other.
And now I’m working on a history (biography?) of Santa Claus, who’s been around, in one form or another, with one name or another, for a lot longer than most people imagine.
