Book of One

Judgment was certain. Desire was not Kalili has been a demon since the beginning of history—and she is very good at her job. Assigned to corrupt a future pope in tenth-century Rome, she expects boredom, excess, and the usual petty sins of men who crave power. What she does not expect is an angel sent with explicit orders to kill her. Faith is everything Kalili is not: newly arrived, rigidly principled, and bound by rules she barely understands. She should be an executioner. Instead, she hesitates. She doubts. And in that hesitation, something dangerous begins. As Rome churns with ambition, corruption, and desire, Kalili and Faith are drawn into a collision neither side intended—one that threatens not just their lives, but the fragile balance between Heaven and Hell itself.
