What Happens, Part by Part (Contains Spoilers)
Wendlyn
Grieving her friend Nehemia, Celaena arrives in Wendlyn, supposedly to kill its royal family. Instead she seeks out Maeve, her aunt and queen of the Fae, hoping to learn about the dark Wyrdkeys. Maeve agrees to help only if Celaena trains with Rowan, one of her warriors, to master her powers. Celaena is reluctant to face her past.
Training
Rowan is harsh, and the two clash constantly. Celaena works in the kitchens at a remote fortress and slowly opens up to the people there. Through training, she learns to control her fire magic and to face memories of her family's murder. She begins to accept that she is Aelin, the true heir of Terrasen.
Manon
In another storyline, Manon Blackbeak, heir of a clan of Ironteeth witches, competes to ride wyverns for the king's army. She bonds with an unusual wyvern named Abraxos. Manon is ruthless and loyal to her clan, but she begins to question the king's plans, which include breeding new monstrous creatures.
Danger at home
In Rifthold, Chaol and Dorian learn more about the king's dark magic. Dorian discovers that he has powerful magic and falls in love with a healer, Sorscha. Chaol works secretly with rebels. Aedion, Aelin's cousin, serves the king as a general but secretly plots to restore her throne.
Aelin rises
Dark creatures called the Valg attack the fortress in Wendlyn. Celaena, now accepting her name as Aelin, uses her fire to defeat them. Back in Rifthold, the king discovers Dorian's magic, executes Sorscha and enslaves Dorian with a dark collar. Chaol flees. Aelin declares that she is ready to reclaim her throne.
