The Song of Achilles by Madeline Miller retells the story of the Trojan War from the perspective of Patroclus, focusing on his deep, lifelong love and relationship with the demigad hero Achilles, transforming the epic myth into a personal tragedy about love, destiny, pride, and loss, culminating in their fated deaths at Troy. It covers their childhood, training, the war's horrors, Patroclus's death in Achilles' armor, and Achilles' subsequent grief-fueled revenge and death, ending with their reunion in the underworld.
