A Court of Frost and Starlight is a novella that follows Feyre, Rhys, and their inner circle as they rebuild the Night Court and the world following the war. Set during the Winter Solstice, the story provides a respite between the action-packed novels, offering a peek into the characters' regular lives. Feyre navigates her first Winter Solstice as High Lady and finds that those dearest to her are still coping with deep wounds from the past, which will impact the future of their Court. The book also sets the stage for the next full-length novel, "A Court of Silver Flames," focusing on characters like Nesta, who is struggling to move forward.
