Louella Twig is the only witch of her kind, much to the disappointment of her former mentor and her previous academic ambitions. While others connect to nature as their source of magic, Louella has an affinity with books. Denied her graduation broom, Louella carves a new path using her talent, creating a magical ambulatory bookshop that travels throughout the realm uniting readers with stories.

She lives a cosy, stable life, until she collides - quite literally - with a mysterious man between the Romance and Adventure aisles. Everett Sharp is handsome, charming ... and a rogue on the run. He's absolutely not someone Louella wishes to share either an adventure or a romance with. But then her old mentor arrives with a desperate request: a valuable grimoire has been stolen and there is only one witch who can retrieve what has been lost ... a witch who now finds herself in need of a bandit with experience.

Together with friends both old and new, Louella and Everett embark on an adventure across the four kingdoms, encountering whimsical creatures, a flying greenhouse full of plant pirates and a magical World's Fair. Along the way, Louella starts to wonder if this new chapter of her life could include some romance after all ...
