The Ruin of Beasts2023

The House of Hua made a binding promise with a demon—in exchange for strength and a lasting legacy, the family's descendants must work to seal away the eldritch being known only as Nuawa, a creature that's long chafed against its captivity and has at last broken free. It will not rest until the Huas are scorched, the family name cast into oblivion. Viveca, Olesya, and all their retainers must marshal their every resource if they want to destroy Nuawa for good. But it has grown arrogant and potent, and at its side stands a mage far more powerful than any other the Huas have ever faced. Now, more than ever, both sisters stand to lose everything.
