Bianca Mortlake is the first Moonborn magician born in Alvion in more than a thousand years, a power so rare that even the histories cannot say what she can do.
In a realm where magicians blessed by the seven planets rule beside kings—those of Jupiter shaping luck, Saturnborn speaking with the dead, and Venusborn reading desire—she has lived quietly, far from court.
A chilling summons calls her back to a palace where two queens have already met the executioner’s blade and standing near the king can be a death sentence.
As ruthless royals and courtiers pull power back and forth, she must depend on Roland, the maddening Venusborn who trained beside her and is the last person she wants at her side.
Something is terribly wrong in Alvion, and only this moon-blessed magician and her oldest rival can keep the court, and each other, from the dark fate they see written in the stars.
