As I've said before, I love a good retelling of the Greek myths and legends, and this one is a very entertaining spin on the story of Hermione, daughter of Helen of Troy. She has not always fared well by other storytellers (looking at you, Euripides) so it's nice to hear her side of the story for once.
But when it comes to Clytemnestra, it doesn't matter whose version you read. She's up up there with Medea. Once a crazy axe lady, always a crazy axe lady.
