Lettering brings together series with different art on the covers. Designing lettering for a book series is a different challenge altogether. A series needs cohesion: a unifying element that ties multiple volumes together while leaving room for each book’s personality to shine. Lettering plays a key role in building this visual identity. It establishes continuity across covers, conveys the overarching mood of the series, and makes the books instantly recognizable as part of a whole.
