For centuries, the Nushtonia remained sealed, a cursed prison forged from blood-oaths, broken promises, and the darkest magic ever wielded by the djinn. It was never meant to be opened.Opening the prison meant releasing Raja, the ancient ruler of the realm of the dead.

Now Raja walks free, and the corruption unleashed with him is spreading across the realms like rot through roots. Magic is twisting. Mountains are whispering. And something old and hungry is waking beneath the surface of the world.

To save an innocent life, Myanin sacrificed herself to the living prison known as the Nushtonia. But she did not enter alone. Inside the sentient book, two are forced to confront the oaths, regrets, and truths they have spent centuries trying to bury. The deeper they journey into the prison, the harder it becomes to ignore the dangerous connection growing between them.

Meanwhile, trapped within the Troll Realm while corruption spreads beneath the mountains, Nick and Kara fight to protect both their unborn child and the fragile peace holding their allies together. Something beneath the earth has taken notice of Kara… and it is hungry.

As old powers rise and realms edge closer to war, the Grey Wolves and their allies are about to learn a devastating truth.

Some oaths do not break quietly. And some loves were never meant to survive.
