Maybe, unlike me, you paid attention during the section on classical Greek literature in high school English. Perhaps you were not bored by Edith Hamilton's Mythology, a standard classroom text that takes exciting stories and neuters them with lifeless prose.
(I am working off memories from a quarter century ago, so if you would like to defend Hamilton from my slander, I am willing to listen.)
Madeline Miller is the glorious opposite of that experience. She is astonishingly good: taut prose, rich atmosphere, tight plotting, and characters who feel like real people.
The Song of Achilles is told from the perspective of Patroclus, who is banished after accidentally killing another child. He is exiled to the court of Peleus, whose son Achilles is preternaturally beautiful and athletic. This can happen when your mother is a goddess.
Patroclus and Achilles become friends and eventually lovers. If you know The Illiad, you know how this story goes. They sail to Troy to make war after Helen runs away with (or is kidnapped by?) Paris. Prophecy says the Greeks can't win the war without Achilles... but prophecy also says Achilles is fated to die there.
This is an exceptionally good book, centered around a grueling war and a queer love story that you want to succeed, even though you it will end in tragedy. And Frazer Douglas's narration of the audiobook is stellar.
When Covid first hit, I started doing book talks on social media as a way to keep in touch with people. I never got out of the habit. I don't discuss books by my clients, and if I don't like a book, I won't discuss it at all. While I will sometimes focus on craft or offer gentle critical perspectives, as a matter of professional courtesy, I don't trash writers. Unless they're dead. Then the gloves come off.
