From The Jacket:
Madeline Miller's Circe meets Cersei Lannister in a stunning debut following Clytemnestra, the most notorious heroine of the ancient world and the events that forged her into the legendary queen.

You were born to a king, but you marry a tyrant. You stand by helplessly as he sacrifices your child to placate the gods. You watch him wage war on a foreign shore, and you comfort yourself with violent thoughts of your own. Because this was not the first offence against you. This was not the life you ever deserved. And this will not be your undoing. Slowly, you plot.

But when your husband returns in triumph, you become a woman with a choice.

Acceptance or vengeance, infamy follows both. So, you bide your time and force the gods' hands in the game of retribution. For you understood something long ago that the others never did.

If power isn't given to you, you have to take it for yourself.
