Cassian trains Feyre in hand-to-hand combat. As they spar, Feyre muses on her decision to leave Tamlin. Her anger at Tamlin burns in her until it literally burns away Cassian’s sparring pads, her gifted power from the Autumn Court. Feyre finally expresses her foundational guilt: “It should have been me” (297); she wishes she had died rather than kill the faeries Under the Mountain. Rhys tells her she must learn to accept her actions in order to survive. He instructs her to harness his power, the power of darkness. She can only imagine the darkness of a prison cell, so Rhys summons a serene darkness filled with twinkling starlight.

Feyre continues her training with Cassian and Rhys. Azriel is glum because his spies have made little progress ascertaining the location of the mortal half of the Book of Breathings. Rhys receives word from the Summer Court, and he, Feyre, and Amren plan to travel there—Feyre to locate the Fae half of the book, and Amren for subtle intimidation. Cassian worries about the political implications of having Feyre as an official representative of the Night Court.
