Sarah J. Maas

No masters. No limits. No regrets. In this sweeping fourth installment, Celaena Sardothien has fully embraced her true identity as Aelin Galathynius, the lost Queen of Terrasen — and she has returned to the empire with vengeance in her heart. She will fight for her cousin, a warrior prepared to die for her. She will fight for her friend, trapped in an unspeakable prison. And she will fight for her people, enslaved under a brutal king and desperately awaiting their queen’s return. Packed with brooding tension, twisty plot turns, lush world-building, and snarky banter, Queen of Shadows is a passionate, agonizing crescendo that raises the stakes higher than ever before.
