Descent

The Mother. A titanic organism, humanity's home and ravenous god. Housing sprouts like fungus from flesh, wrapped in membranes, supported by cartilage. No stone. No metal.

Within her pulsing bowels, Thandie is a cartographer, not a hero. She maps the veins of the Greater Membranes, hunting for food. She shuts her eyes during executions, obeys her superiors, prays she won't be selected before forty.

But when she discovers an epochal threat and is ordered to stay silent, she can no longer stand aside.

Hunted from the high towers of the professions down to the sewers, fleeing through living conduits and breathing pits, she becomes the heretic cartographer.

She refuses to close her eyes anymore: if she doesn't find a way to stop them, she'll be selected next.
