Finally the 4th volume of the Fantasy.Saga by Sarah J. Maas

The terrible battle against Hybern has not left Feyre, Rhys and their companions unscathed. Nevertheless, they give their all to rebuild the Court of Night and maintain the uncertain peace in the realm. The upcoming winter solstice offers the perfect opportunity to finally unwind and celebrate together. But even the festive atmosphere can't hold back the shadows of the past - for Feyre's friends carry deep wounds and her allies from the war are far from to be trusted.
