The clean bold colours of the covers, clever spine effect, large series numbers, and the sassy small format make a strong series statement. The back cover colour of each book is the same as the front cover of the next book in the series. The hand-lettered front cover text, chapter & part titles and chapter numbers reflect the uniqueness of the series and its approach to storytelling. The simple, clean text design combines visual and textual narrative to entice reluctant readers. The balance of illustration and text, and the page-turn effect were finely honed to enhance the reading experience.
