In a world scarred by the devastating rift known as "The Firestorm," Kiona walks a perilous line between two ancient enemies. As the descendant of Saint Sabre of Gardenia and Jehanne Darc of the Ur Alliance, Kiona grapples with the weight of expectation, a living bridge where history's embers ignite her destiny.
When Queen Marieanne's brother, Charles, extends a perilous invitation, Kiona finds herself at the heart of France-Orl ans-where whispers of revolution clash with the pride of monarchy. Tasked with a mission fraught with danger, she must warn the spoiled queen and the fervent revolutionaries of the advancing threat posed by Cynthia Caesar's formidable Northern Roman Empire. As shadows of the past loom larger, Kiona must confront not only the schemes of an ambitious adversary but also the raging flames of her own conflicted heritage.
