Heir of Fire

Sent across the sea on orders she has no intention of following, Celaena arrives in Wendlyn chasing a name she has avoided for ten years. Meanwhile, Chaol remains at the glass castle, pulled between the king he serves and the truth he has uncovered; Dorian is learning he has inherited something the king has spent a lifetime outlawing; and in the north, the Ironteeth witches are stirring.

Heir of Fire is the structural turn of the series. Three continent-spanning plotlines run in parallel, and the scope expands from palace intrigue to full epic fantasy — introducing Rowan Whitethorn, Manon Blackbeak, and the Fae bloodlines that drive the remaining four books.
