Song of Achilles (by Madeline Miller)

I loved Circe so of course I had to read Song of Achilles! It is the story of Achilles and Patroclus before and during the Trojan War, told from the point of view of Patroclus. It's wonderfully humane, like Circe, bringing the mythology to vivid life. The characters feel lived-in and real, despite the mythological subject matter. I didn't fall in love with it the way I did with Circe (a very high bar) but I enjoyed it very much.
