When Sage Greene turned the tender age of six, she found out who she was, at thirteen she learned what was expected of her, and at eighteen, she rebelled. Considered royalty among special organizations of librarians that contain the convicted supernatural in books designed as prisons, Sage has a legacy to uphold, take pride in, and pass down to another generation. Coming from a long line of word binders-librarians that imprison enchanted criminals into books by spells, Sage wants to escape into a book herself. Finding a way to vent her promise of a secure, but monotonous future, Sage decides to secretly enroll in a martial arts class designed for guardians who protect libraries housing the prison-books secretly kept in normal libraries. Sage's desire for adventure comes unexpectedly at the annual Ball where high society librarians make their first debut. Along with all the gown-wearing girls, is something else being displayed. The Fan of Change-a fan crafted to change anyone's appearance in the matter of a flick, and also, the newly acquired item to the guardians' collection of magical implements. And with such a prize, comes temptation of thieves. When a heist unfolds to steal the Fan, sage puts her two months' worth of training to use only to be captured. A world she never knew opens when she's rescued by a vigilante guardian. What she thought was always right in the way of guardians and librarians, swiftly turns sour. Sage is left with a decision that will not only affect her life, but librarians and guardians everywhere.
