Tower of Dawn

Tower of Dawn is a fantasy novel by the American writer Sarah J. Maas, published in 2017 and part of the Throne of Glass sequence.

Chaol Westfall has always understood himself through his loyalty and his position as captain of the Guard. That has gone: the glass castle is destroyed, the soldiers he commanded are dead, and the king who could have killed him left him alive with a body that no longer works. Recovery, if it comes at all, is with the healers of the Torre Cesme, the stronghold of the empire on the southern continent. Chaol travels there with Nesryn, and what the two of them are doing is not only medical. War is coming to Dorian and Aelin at home, and their chances may depend on whether Chaol and Nesryn can persuade the rulers of the south to take their side.
