The description comes from the publisher:
Anger.
Anger turns the soul into a raging fire that can never be extinguished. This is the whole world of Rin. She grabbed fate by the throat and wrenched her future out of him – she got to the Sinegard Academy and then continued, day after day, to finish it. Just to watch her friends die one by one. To see the mountains made of the corpses of their countrymen. To become a being, capable of burning an entire nation of invaders in an act of unimaginable revenge.
Now she has nothing left but to retaliate against the last traitor, Empress Su Daji. And the constant struggle with the Phoenix, who constantly demands victims. The moment she surrenders to him, her body will only become an instrument and will burn everything and everyone. And when the whole world turns to ashes, Rin herself will dream of death.
