A throne beneath a vast shadow. A church thirsty for blood. An angel-turned-human who could break the dark magic… if she survives.

Late Middle Ages, Castile, Spain. Isa is confident in her gift of prophecy. Allowed to grow up free of religious contamination, the young peasant woman longs to wander freely and commune with nature. But when the queen of the realm seeks her out and begs for spiritual guidance, the humble girl plunges into a world of lust, intrigue, and political backstabbing.

Condemned by Rome as a witch, Isa’s only prayer for survival lies in her complex relationship with her troubled liege lady. But her hope shatters when she dreams of a fiery death at the hands of the vengeful Catholics.

Can she cling to faith while caught in the clutches of endless malice?
