Position to one era shelf per series, not per book
Pick a single “main shelf” era for your author brand in 2026 (for example: WWII resistance, Victorian/1920s historical mystery, or American 20th-century women’s stories). Your backlist titles should look like they belong together on the retailer’s era shelves, not like one-off experiments. Practically: keep the same cover style language within the series, keep the blurb template era-first, and repeat a consistent naming pattern (for instance: [City/Region] + [Decade/EVENT marker] + [Character role]). This matters in historical fiction because readers often browse by time period first, then decide whether the writing matches their tolerance for research density and historical tone.
