Meet Celaena Sardothien. Beautiful. Deadly. Destined for greatness. In the dark, filthy salt mines of Endovier, an eighteen-year-old girl is serving a life sentence. She is a trained assassin, the best of her kind, but she made a fatal mistake. She got caught.

Young Captain Westfall offers her a deal: her freedom in return for one huge sacrifice. Celaena must represent the prince in a to-the-death tournament - fighting the most gifted thieves and assassins in the land. Live or die, Celaena will be free. Win or lose, she is about to discover her true destiny. But will her assassin's heart be melted?

Eighteen-year-old Celaena Sardothien is bold, daring and beautiful – the perfect seductress and the greatest assassin her world has ever known. But though she won the King's contest and became his champion, Celaena has been granted neither her liberty nor the freedom to follow her heart.

Celaena faces a choice that is tearing her to pieces: kill in cold blood for a man she hates, or risk sentencing those she loves to death. Celaena must decide what she will fight for: survival, love or the future of a kingdom. Because an assassin cannot have it all ... And trying to may just destroy her.

Celaena Sardothien is bound to serve the tyrant who slaughtered her dear friend. But she has vowed to make him pay. The answers Celaena needs to destroy the king lie across the sea Wendlyn. And Chaol, Captain of the King's Guard, has put his future in jeopardy to send her there. Yet as Celaena seeks her destiny in Wendlyn, a new threat is preparing to take to the skies. Will Celaena find the strength not only to win her own battles, but to fight a war that could pit her loyalties to her own people against those she has grown to love?

Everyone Celaena Sardothien loves has been taken from her. Now she returns to the empire – to confront the shadows of her past ... Bloodthirsty for revenge on the two men responsible for destroying her life, and desperate to find out if the prince and his captain are safe, Celaena returns to Rifthold.

She has accepted her identity as Aelin Galathynius, the lost Queen of Terrasen. But before she can reclaim her throne, there are dark truths to learn and debts to be paid. Aelin must stay hidden beneath her assassin's hood and draw on her mortal strength as Celaena to prevent the King of Adarlan from tearing her world apart. Only then can she fight for her people.

The long path to the throne has just begun for Aelin Galathynius. As the kingdoms of Erilea fracture around her, enemies must become allies if Aelin is to keep those she loves from falling to the dark forces poised to claim her world.

With war looming on all horizons, the only chance for salvation lies in a desperate quest that may mark the end of everything Aelin holds dear. Will Aelin succeed in keeping her world from splintering, or will it all come crashing down?

Chaol Westfall has always defined himself by his unwavering loyalty, his strength, and his position as the Captain of the Guard. But all of that has changed since Aelin shattered the glass castle, since Chaol's men were slaughtered, since the King of Adarlan spared him from a killing blow, but left his body broken.

Now he and Nesryn sail for Antica – the stronghold of the southern continent's mighty empire and of the legendary healers of the Torre Cesme. It's Chaol's one shot at recovery, and with war looming back home, Dorian and Aelin's survival could depend on Chaol and Nesryn convincing Antica's rulers to ally with them. But what they discover there will change them both – and be more vital to saving Erilea than they could have imagined.

Aelin Galathynius's journey from slave to assassin to queen reaches its heart-rending finale as war erupts across her world. She has risked everything to save her people – but at a tremendous cost. Locked in an iron coffin by the Queen of the Fae, Aelin must draw upon her fiery will to endure the months of torture inflicted upon her. The knowledge that yielding to Maeve will doom those she loves keeps her from breaking, but her resolve is unravelling with each passing day

With Aelin imprisoned, Aedion and Lysandra are the last line of defence keeping Terrasen from utter destruction. But even the many allies they've gathered to battle Erawan's hordes might not be enough to save the kingdom. Scattered throughout the continent and racing against time, Chaol, Manon, and Dorian must forge their own paths to meet their destinies. And across the sea Rowan hunts to find his captured wife and queen – before she is lost to him. Some bonds will deepen and others be severed forever, but as the threads of fate weave together at last, all must fight if they are to find salvation – and a better world.
