I love love love The Song of Achilles by Madeline Miller, so I've been looking forward to finally getting to this one.

TSoA edges out over Circe for how much I enjoyed it but only a little. 
This is a little more abstract because of course we're following immortals so timelines are pretty vague, but Circe herself keeps things grounded. I'm also not a Classicist, I have only the general knowledge of some of the more well known Greek myths, Kronos and Zeus, the minotaur, Troy, etc., so I can't comment on the accuracy of this retelling.

All that being said, I just related to Circe as a character. How she felt like an outsider to her community of gods and titans. I got upset at how her family would treat her and how every time she would find someone she thought loved her genuinely, they would ultimately leave her behind. We see Circe go through many different phases of grief and anger, and also empowerment and vengeance, but also moments of happiness.

I loved the ending!
