Circe is born into Helios's divine household. Her voice sounds mortal, her appearance is plain, and she is immediately marked as insufficient. She watches her brilliant siblings Pasiphae and Aeëtes and learns the first lesson of power: she has none.

Prometheus is dragged through Helios's hall, bound and bloodied, on his way to eternal punishment for giving fire to mortals. Circe, watching, is moved to speak to him — an act of empathy that marks her further as outside divine norms.

Circe falls in love with the mortal fisherman Glaucos. When he faces death, she discovers and uses pharmaka to transform him into a sea god. Glaucos forgets her almost immediately.

Circe, in jealous desperation, uses pharmaka to transform the nymph Scylla into a monster. The act reveals the full scope of her power — and its destructive potential when untempered by wisdom.

Circe arrives at her island exile. She begins the long work of learning her craft alone — gathering herbs, speaking to animals, building a life from what the island offers.

A ship arrives at Aiaia. Circe offers hospitality; the sailors assault her. She transforms them into pigs. This is the origin story of her most famous myth — and the novel's most explicit treatment of sexual violence and its aftermath.

Daedalus arrives at Aiaia. The craftsman and the witch recognize in each other a kindred form of power — one that is made, not given. His son Icarus is restless, reaching. Circe watches what happens to boys who fly too high.

Jason and Medea stop at Aiaia. Circe performs the ritual of absolution for the murder of Medea's brother Absyrtus. She sees what Medea is — brilliant, powerful, terrifyingly in love — and recognizes a version of her earlier self.

Odysseus's crew lands on Aiaia, invades her home, and Circe transforms them into pigs. Odysseus arrives protected by the herb moly and is immune to her pharmaka. They negotiate. The dynamic of the novel's central relationship begins.

Odysseus and Circe live as lovers for a year on Aiaia. He tells her stories; she tells him truths. She begins to understand that he is always, at some level, already leaving.

Before leaving, Odysseus must descend to the Underworld. Circe instructs him in the ritual and preparations. He goes; he returns. Then he leaves. Circe enters a grief she will not name.

Circe is pregnant and will not leave Aiaia to give birth among gods. She delivers Telegonus alone and raises him in isolation. Hermes brings the prophecy: the boy will accidentally kill his father.

Circe's sister Pasiphae sends word from Crete. The Minotaur has been born. Circe is summoned to help and refuses — but the chapter expands the world beyond Aiaia and establishes the political costs of divine family membership.

Telegonus grows and demands to leave Aiaia to find his father Odysseus. Circe holds him back with the prophecy, with fear, with love. He resents her for it. The tension between protection and imprisonment becomes the chapter's central question.

Word comes: Telegonus has arrived in Ithaca. Odysseus, not recognizing him, attacked the stranger. Telegonus's spear — tipped with a stingray's barb, Circe's poisonous gift — killed him. Telegonus returns to Aiaia with Odysseus's body, Penelope, and Telemachus.

Penelope, in her grief, begins to unravel the weaving of her disguises — showing Circe who she actually is. Circe, watching, recognizes in Penelope a form of endurance she had not previously valued: the power of the steady witness.

Telemachus comes to Circe as a student. She teaches him pharmaka, but what he really learns — and what she learns from teaching him — is that power requires the willingness to be changed by what you practice.

Athena appears on Aiaia, hostile and possessive of Telemachus. She warns Circe away. The threat clarifies what is at stake and what Circe will have to choose between.

Penelope decides to stay on Aiaia rather than return to Ithaca. She and Telegonus form an unexpected connection. Circe understands that not all transformations require pharmaka.

What has been growing between Circe and Telemachus becomes explicit. She must hold two things simultaneously: the genuine nature of what she feels, and the impossibility of its future without a radical choice.

Circe makes her choice. She uses her pharmaka — with centuries of accumulated knowledge behind it — to transform herself from immortal to mortal. The witch's final act is on herself.
