The Crimson Heritage

When the global grid collapses and law dissolves overnight, a bride imprisoned for her husband's savage murder escapes into a world descending into primal chaos. She discovers that her violent impulse is not a sin, but a centuries-old genetic inheritance waiting to bloom. As the thin veneer of civilization shatters, she embraces the darkness in her blood to forge the first brutal order of the new world, where the killing gene writes the only law that matters.
