The Ghosts in the Flames by Seann Barbour
For centuries, the Four Kingdoms have lived in fear of the dragon Raksen-Kal, who roosts upon the peak of the Black Mountain. To satiate his hunger, a noble maiden is sent to the dragon as tribute every Autumn, with each of the kingdoms trading off the duty of sending the sacrifice year by year.
Shivuri is the youngest princess of Endaru, the smallest and poorest of the Four Kingdoms. Today, her cousin is sent to the dragon, and in four years’ time, she will be as well.
As the day of her death draws ever closer, the young princess seeks solace in darkness, and explores the forbidden art of witchcraft. In doing so, Shivuri learns of secrets that would once have filled her with terror– and of freedom that she never before could have imagined.
