The clash between Bren and Loki rages on, their fury spinning into a cataclysmic force more destructive and deadly than any of us could have foreseen. Bren is the only immortal in the nine worlds who can restrain it… but not for long.

As a sinister entity stalks us in the depths, the unspoken pull between us intensifies, revealing its own dark origin and leaving us nowhere to run.

Every truth we uncover rolls into a deeper mystery, but the existence of everyone we love, everything we know hinges on our survival. We are staring directly into the eye of a storm, and we cannot back down. But conquering the tempest may require an unthinkable sacrifice.
