The Foxglove King (The Nightshade Crown Book 1)

Lore escaped a death-magic cult in the catacombs beneath Dellaire at thirteen and has spent ten years hiding. Her ability to raise the dead—a power called Mortem—ties her to the city, where she survives by running poisons. When her magic is exposed, the Presque Mort, warrior-monks serving the Sainted King, capture her. Instead of execution, King August offers Lore a choice: use her power to investigate mysterious deaths occurring in villages across the country's outskirts and identify who in his court is responsible, or face the pyre. She accepts and enters the royal court, a world of politics, religion, and deception. Guarded by Gabriel, a duke-turned-monk, and frequently encountering Bastian, the King's heir, Lore navigates the court's opulent and debauched society while pursuing forbidden connections. Meanwhile, the life she abandoned in the catacombs draws closer, threatening to catch up with her.
