A Court of Silver Flames by Sarah J. Maas

Nesta Archeron has always been prickly—proud, swift to anger, and slow to forgive. And since the war—since being made High Fae against her will—she’s struggled to forget the horrors she endured and find a place for herself within the strange and deadly Night Court.

The person who ignites her temper more than any other is Cassian, the battle-scarred, winged warrior who is there at Nesta’s every turn. But her temper isn’t the only thing Cassian ignites. The fire between them is undeniable, and it only burns hotter as they are forced to work closely together.

As the threat of war casts its shadow over them once again, Nesta and Cassian must battle monsters from within and without as they search for acceptance—and healing—in each other’s arms.
