Tower of Dawn (Throne of Glass, #6)

by Sarah J. Maas

Chaol glanced to Yrene, smiling serenely at the sea, then to the note. To the handwriting he knew as well as his own.

Chaol looked up at last, blinking away tears as he scanned his wife’s face. Every beautiful line, those golden eyes. A gift. A gift from a queen who had seen another woman in hell and thought to reach back a hand. With no thought of it ever being returned. A moment of kindness, a tug on a thread … And even Aelin could not have known that in saving a barmaid from those mercenaries, in teaching her to defend herself, in giving her that gold and this note … Even Aelin could not have known or dreamed or guessed how that moment of kindness would be answered.

A moment of kindness. From a young woman who ended lives to a young woman who saved them.
