In the heart of a world illuminated by the magic of light, Gavin Guile reigns as the Prism, a figure of unmatched power and enigmatic charisma, holding together a fragile peace with the sheer force of his will. As the high priest and emperor, Guile's dominion is absolute, his influence unchallenged, and his secrets as deep and dark as the shadows that dance at the edge of his light. But even the brightest light casts a shadow, and Guile's time is running out. With only five years left to live, a past war’s consequence comes to haunt him—a son he never knew he had, a living testament to the precarious balance between peace and the potent stirrings of a war that could unravel everything. This son, born of blood and specters from a time best left forgotten, emerges as the pivot upon which the fate of the world teeters precariously. Guile finds himself torn between the love he never knew he could feel and the heavy mantle of power he has borne for so long. With every decision weighed by the scales of potential devastation, The Black Prism unfolds as a mesmerizing tale of magic, ambition, sacrifice, and the quest for redemption. Brent Weeks weaves a story that is as much about the struggles within the human heart as it is about the battles that rage in the world outside, crafting a compelling narrative that asks whether peace is truly possible and at what cost it comes.
