In the pristine city of the Aurelian Concord, orphan seamstress Madeleine Butler guards a dangerous secret: a magical light that burns within her, a power she has been taught is a shameful, corrupting illness. Her only hope for a normal life lies in the arms of Captain Christian Underwood, a golden hero who promises escape and a future free from fear. But in a city built on order and perfection, the deepest secrets are often the deadliest.
When the formidable Sovereign Victor Paige arrives from the blighted, dying kingdom to the north, his stormy gaze pierces through Madeleine's carefully constructed facade, recognizing the very power she hides. In a stunning public confrontation, he shatters her world, invoking an ancient pact to claim her as his own. Abducted and declared his betrothed, Madeleine is dragged into the shadows, her hope for rescue dying with a final, triumphant look from the man she thought was her savior.
Trapped in the gothic, decaying Ashen Spire, she is a prisoner in a land being consumed by a magical plague. The ruthless shadow king offers her a brutal bargain: use her life-giving magic to become the cure for his kingdom and for the curse that is killing him. He is her captor, yet he may be the only one telling her the truth about her past and the genocide that birthed her enemy's empire.
As the Aurelian army marches to "rescue" her and bring a cleansing fire to the north, Madeleine must choose between the beautiful lie she loved and the brutal truth that now holds her captive. To survive, she must unleash the full, terrifying force of her magic, a power that could save a kingdom or burn the world to ash.
