Chapter Fifty-Six

A month into winter training, Nesta has grown stronger and healthier while continuing her sexual relationship with Cassian and learning dances with Mor in preparation for the Winter Solstice ball. Gwyn gifts Nesta and Emerie with chapters from Merrill's book about the rebirth of the Valkyries, while Emerie experiences trauma triggers in the library's depths. After Cassian leaves for Illyrian outposts, Nesta confronts her fear of fire and makes peace with her trauma, leading the House to guide her to its heart—a pit of darkness—where she connects with the House itself as a kindred, damaged soul.

The chapter opens with Nesta thriving physically after a month of Valkyrie training in winter conditions, despite her complicated feelings about Cassian's physical passion and his refusal to stay with her afterward. She continues dance lessons with Mor, learning various court dances through the Veritas orb, and has a breakthrough moment when Mor helps her find appropriate attire for the Winter Solstice ball and reveals her name preference. In the library, Gwyn surprises Nesta and Emerie with a handwritten gift: they have been included in Merrill's book about the Valkyries' rebirth, with Gwyn having written their chapter herself. The moment deeply moves both women. However, Emerie becomes distressed on the lower levels, experiencing visceral trauma responses triggered by the library's darkness—hearing her abusive father's voice. Nesta comforts her and moves them to a higher level. That evening, after receiving a note that Cassian must stay in Illyrian outposts, Nesta attempts to face her fire trauma by requesting the House create a small fire and using breathing techniques to sit with her discomfort. She succeeds in enduring it without fleeing, marking an emotional breakthrough. The House then leaves a trail of evergreen twigs leading Nesta to the library's seventh level and into its darkest pit—the House's heart itself. There, Nesta realizes the darkness represents the House's own trauma and brokenness, and she recognizes their kinship. She extinguishes the lantern, embraces the darkness, and acknowledges the House as both friend and home, experiencing what feels like a comforting touch in response.
