In the shadowed courts of the Obsidian Realm, Lady Vespera is feared as the Queen of Poison. She is a woman whose very breath can wither a garden and whose touch can turn the strongest steel to rust. Adorned in flowing robes of ethereal violet and white, she moves with a lethal grace, holding dominion over the toxic miasmas that seep from the world’s decaying foundations. While the other ruling houses covet gold and territory, Vespera understands that true power lies in the unseen—in the venomous secrets that rot a kingdom from within. When a mysterious, ancient contagion begins to spread, threatening to consume both the high and low-born, the other nobles are forced to kneel before her throne, begging for the very antidote she alone possesses. As she navigates a web of palace treachery and dark conspiracies, Vespera finds that her greatest challenge is not the external threat, but the cold, isolating burden of a heart that has become as toxic as her touch.
