When Lore was thirteen, she escaped a cult in the catacombs beneath the city of Dellaire. And in the ten years since, she’s lived by one rule: don’t let them find you. Easier said than done, when her death magic ties her to the city. Mortem, the magic born from death, is a high-priced and illicit commodity in Dellaire, and Lore’s job running poisons keeps her in food, shelter, and relative security. But when a run goes wrong and Lore’s power is revealed, she’s taken by the Presque Mort, a group of warrior-monks sanctioned to use Mortem working for the Sainted King. Lore fully expects a pyre, but King August has a different plan. Entire villages on the outskirts of the country have been dying overnight, seemingly at random. Lore can either use her magic to find out what’s happening and who in the King’s court is responsible, or die.
