Heir of Fire (Throne of Glass, #3)

by Sarah J. Maas

“There is this … rage,” she said hoarsely. “This despair and hatred and rage that lives and breathes inside me. There is no sanity to it, no gentleness. It is a monster dwelling under my skin. For the past ten years, I have worked every day, every hour, to keep that monster locked up. And the moment I talk about those two days, and what happened before and after, that monster is going to break loose, and there will be no accounting for what I do. “That is how I was able to stand before the King of Adarlan, how I was able to befriend his son and his captain, how I was able to live in that palace. Because I did not give that rage, those memories, one inch. And right now I am looking for the tools that might destroy my enemy, and I cannot let out the monster, because it will make me use those tools against the king, not put them back as I should—and I might very well destroy the world for spite. So that is why I must be Celaena, not Aelin—because being Aelin means facing those things, and unleashing that monster. Do you understand?”
