The Duchess of Thorns and Iron

Betrayed by her family and disfigured by toxic powder, Lilith died a ruined beggar in a freezing woodshed, her bastard sister having stolen her royal betrothal. Gods granted her rebirth. On the morning of humiliation, she grabs her grandmother's druidic apothecary codex. Using toxic botany, she peels away lies and poisons enemies' ambitions. As she ensnares the cold Holy Knight Commander, a dark imperial conspiracy surfaces. Can she cut the rot before it consumes her new home?
