A hunter chases a witch.

A witch hears a spirit.

A spirit seeks a god.

Witches were once slaves, only able to use their magic when their parents commanded it. But there’s a new god in the firmament, and now the witches’ magic is free... and that has transformed them from slaves into threats.

Tara knows that if her mistress’s soldiers find her, they will kill her, even though she is only a harmless air witch. So she flees, alone and pursued by the Duchess’s most dangerous man.

She would have died within hours if not for an unexpected ally: a mysterious spirit only she can see, who claims to have heard the voice of a dying god.

Tara agrees to accompany him on his mission, determined to help the stranger who saved her and to discover the truth hidden behind his blue eyes.
