She who dons the power of the stars above will set this rose garden aflame... and watch it burn. Amelie Hartwin knows everything about the world she lives in. With a historian for a mother, she's learned everything from every book front to back, and puts her talents to use as a swordswoman on the side while living a quiet life with her strict and worried elder sister Emilia. But on the night of a Holy Royal Ceremony, something goes horrifically wrong and the rulers all end up dead, with the kingdom of Arcelia's own queen falling just days later, leaving the nine high kingdoms in shock. And when a group of palace officials reveal that Amelie has been chosen to be the next queen, she realizes that far too much as fallen into her hands... but far too much is at stake to turn back. When she has a violent encounter with a mysterious woman who may have been the one responsible for the killings of the royalty, Amelie is forced to flee into unknown territory with a deadly group of sorcerers on her heels. Injured and running from the vicious woman hell bent on destroying her, Amelie stumbles upon a group of young apprentice mages, studying under the past lover of her beloved queen. Together they uncover an explosive plot to destroy the kingdoms and unearth the very foundations of their world if the mysterious woman is not stopped in time. To make things more complicated, Amelie finds herself falling for the purple eyed, knife throwing warrior Eve Hecate, who seems equally drawn to her. But as the darkness and threat of destruction looms above them, can they outsmart the killer witch before she destroys everything they hold dear?
