A prequel to the bestselling Throne of Glass series.

Celaena Sardothien is her kingdom's most feared assassin. Though she works for the powerful Assassin's Guild and its scheming master, Arobynn Hamel, she yields to no one and trusts only her fellow killer-for-hire, Sam. 

But when Arobynn dispatches her on missions that take her from remote islands to hostile deserts, Celaena finds herself acting independently of his wishes and questioning her own allegiance. If she hopes to escape Arobynn's clutches, Celaena will have to put her faith in her wits and her blade... knowing that if she fails, she'll lose not just a chance at freedom but her life. 

When Feyre kills a wolf, a beastlike creature arrives to demand retribution for it. Dragged to a magical land, Feyre discovers that her captor is not an animal. As she dwells on his estate, her feelings for Tamlin transform from icy hostility into a fiery passion that burns through every lie and warning she's been told about the beautiful, dangerous world of the Fae. But an ancient shadow is growing, and Feyre must find a way to stop it....

Celaena Sardothien won a brutal contest to become the King's Champion. But she is far from loyal to the crown. Though she goes to great lengths to hide her secret, her deadly charade becomes more difficult when she realises she is not the only one seeking justice. Her search for answers ensnares those closest to her, and no one is safe from suspicion - not the Crown Prince Dorian; not Chaol, the Captain of the Guard; not even her best friend, Nehemia, a princess with a rebel heart.

Then, one terrible night, the secrets they have all been keeping lead to an unspeakable tragedy. As Celaena's world shatters, she will be forced to decide once and for all where her true loyalties lie... and what she is willing to fight for. 

Celaena Sardothien has survived deadly contests and shattering heartbreak, but now she must travel to a new land to confront her darkest truth. That truth could change her life - and her future - forever.

Meanwhile, monstrous forces are gathering on the horizon, intent on enslaving her world. To defeat them, Celaena will need the strength not only to fight the evil that is about to be unleashed but also to harness her inner demons. If she is to win this battle, she must find the courage to face her destiny - and burn brighter than ever before. 

In a land where the king rules with an iron hand, an assassin is summoned to the castle. She comes not to kill the king, but to win her freedom. If she defeats twenty-three killers, thieves, and warriors in a competition, she is released from prison to serve as the king's champion. But Celaena Sardothien's fight for freedom becomes a fight for survival, and a desperate quest to root out the evil before it destroys her world.
