Fair is foul and foul is fair.

From the Sunday Times bestselling author of A STUDY IN DROWNING comes a reimagining of Lady Macbeth, Shakespeare's most famous villainess, giving her a voice, a past, and a power that transforms the story men have written for her.

The Lady knows the stories: that her eyes induce madness in men.

The Lady knows she will be wed to the Scottish brute, who does not leave his warrior ways behind when he comes to the marriage bed.

The Lady knows his hostile, suspicious court will be a game of survival, requiring all of her wiles and hidden witchcraft to survive.

But the Lady does not know her husband has occult secrets of his own. She does not know that prophecy girds him like armour. She does not know that her magic is greater, and more dangerous, and that it will threaten the order of the world.

She does not know this yet.

But she will.
