La serie de Sarah J. Maas continúa con el viaje de la hermana de Feyre, Nesta. Un poder insondable. Desde que fue forzada a meterse en el Caldero y se convirtió en alta fae en contra de su voluntad, Nesta Archeron lucha por encontrar su propio lugar dentro del extraño y letal mundo en el que habita. A su temperamento irascible se suma la dificultad para superar los horrores de la guerra con Hybern y todo lo que perdió en ella. Mientras que Cassian, miembro de la Corte Noche de Rhysand y Feyre, es designado para entrenar a la incontrolable Nesta y entre ellos se enciende el más ardiente de los fuegos, las traidoras reinas humanas forjan una nueva y peligrosa alianza que amenaza la frágil paz establecida entre los reinos. Y la clave para detenerlas podría depender de que Cassian y Nesta logren superar sus inquietantes pasados. En un mundo arrasado por la guerra, Nesta y Cassian deberán enfrentarse tanto a sus monstruos interiores como a los que acechan en el exterior, y cada uno buscará la aceptación –y la curación– en brazos del otro. ENGLISH DESCRIPTION Against the sweeping backdrop of a world seared by war and plagued with uncertainty, Nesta and Cassian battle monsters from within and without as they search for acceptance-and healing-in each other's arms. Nesta Archeron has always been prickly-proud, swift to anger, and slow to forgive. And ever since being forced into the Cauldron and becoming High Fae against her will, she's struggled to find a place for herself within the strange, deadly world she inhabits. Worse, she can't seem to move past the horrors of the war with Hybern and all she lost in it. The one person who ignites her temper more than any other is Cassian, the battle-scarred warrior whose position in Rhysand and Feyre's Night Court keeps him constantly in Nesta's orbit. But her temper isn't the only thing Cassian ignites. The fire between them is undeniable, and only burns hotter as they are forced into close quarters with each other. Meanwhile, the treacherous human queens who returned to the Continent during the last war have forged a dangerous new alliance, threatening the fragile peace that has settled over the realms. And the key to halting them might very well rely on Cassian and Nesta facing their haunting pasts.
