Red Calamity. The Split

The final part of the duology "Red Calamity", where we enter the world of demons.

The world is on the brink of catastrophe, and its fate is in the hands of Romain, the heir of the Great House, who has stained herself with an alliance with a demon.

In her veins pulses a foreign essence, and the thirst for blood clouds her mind. Halakhel, a monster in human guise, offers Romain protection and power, but every service has a price.

To stop the invasion of the Black Mother, Romain must accept her new nature and trust Halakhel. But how can she rely on someone whose essence is destruction?
They may save this world. Or destroy it before the Fates' monsters do.
