A Court of Thorns and Roses #5 A Court of Silver Flames (original) Sarah J. Maas

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.
