DESCRIPTION Some witches cast spells. Others slay kings. A mysterious Grimoire. A marriage full of dark secrets. A History sculpted by a quartet of ancient Sister witches. For three hundred years, Sister Autumn has incited wars, burnt villages, killed kings, and released plagues at the bidding of the Grimoire. Meanwhile, her Sister Winter, Sister Spring, and Sister Summer have brought forth only peace. When an Order from the Grimoire sends Agatha to the Kingdom of Merveille, she already anticipates the worst. Unless she wants to face the wrath of the Goddess, Agatha must keep her head down and do as she’s commanded. But when the Grimoire Orders her to marry a pompous prince and play the role of a peasant “accepted” by vicious aristocrats, she finds herself at the center of a war between the classes and an age-old prophecy. Within the court, many players harbor dark secrets—including her new husband. With her newfound influence, Agatha joins forces with the city’s Blacklisted in order to blur the lines between the common man and the elite, unravel the mysteries in her marriage, and decide once and for all if she will defy the Grimoire and face the brutal consequences. As secrets unfold, will Agatha continue to slay on behalf of the Grimoire, or forge an uncharted History with her unlikely allies?
