The Gemmorah brothers just pulled off the greatest caper in history - before betrayal opened its maw. Now, one brother rots in slavery, harvesting fungus from the walking dead, and the other lies in solitude, dying by inches.

The vengeful sun has forced their people underground, down where massive predators are stirring. The water is gone, Soulstorms savage the surface, and the meat that the Brotherhood summons through the Gate is getting more and more perverse.

Mia, torn from her world and into this scorched nightmare, is searching for her missing betrothed. But something else has travelled with her: coiled around her soul is a dark passenger from the void between worlds. It hungers for destruction, and it's getting stronger.
