After serving the Linden Order as a living remedy for a century, Aconia is betrayed, stripped of her Soul-Seed, and cast into the wasteland to die. But she is no harmless healing flower—she is the last survivor of a deadly foxglove bloodline. Saved by wasteland alchemist-mechanist Vincan, she rebuilds her core, reclaims her poison, and rises from hunted victim to Poison Queen. As a century-old blood-harvesting conspiracy emerges, Aconia returns to the Dome City to destroy the false order that stole her family, her power, and her life.
