This is the first novella in the ACOTAR series.
In this companion tale to the bestselling A Court of Thorns and Roses series, Feyre, Rhys and their friends are working to rebuild the Night Court and the vastly changed world beyond after the events of A Court of Wings and Ruin.
But Winter Solstice is finally near, and with it a hard-earned reprieve. Yet even the festive atmosphere can’t keep the shadows of the past from looming. As Feyre navigates her first Winter Solstice as High Lady, she finds that those dearest to her have more wounds than she anticipated o scars that will have a far-reaching impact on the future of their court.
I really enjoyed this novella. Frost and Starlight is set after ACOWAR and it switches perspective between Freye and Rhysand.
It does expand on relationships seen throughout the series which I really enjoyed.
