To save the light, she must become the darkness. Elara is a Shadow, a glitch in the perfect, glowing tapestry of Aethelgard. Born without a flicker of magic, she spends her days in the suffocating heat of the foundries, forging jewelry for the Glow-born elite. But when her younger sister is struck by the Star Rot, a lethal plague that turns veins into burning glass, Elara is forced to crawl into the heart of the enemy's fortress. Caelum, the King's most ruthless butcher, doesn't kill Elara when he catches her. Instead, he recognizes the terrifying vacuum within her: a Void capable of devouring the sun. He offers a blood-stained contract: a marriage of convenience, a seat at the Solar Court, and the cure for her sister As Elara navigates a gilded cage of masks and mirrors, her forbidden attraction to the General grows as fierce as the hunger in her blood. In a kingdom that fears the dark, Elara must decide if she is a pawn in Caelum's revolution or the eclipse that will bring the throne to its knees.
