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...

"The long path to the throne has only just begun for Aelin Galathynius. Loyalties have been broken and bought, friends have been lost and gained, and those who possess magic find themselves at odds with those who don't. 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"--

After she has served a year of hard labor in the salt mines of Endovier for her crimes, Crown Prince Dorian offers eighteen-year-old assassin Celaena Sardothien her freedom on the condition that she act as his champion in a competition to find a new royal assassin.

With Aelin locked in an iron coffin by Queen of the Fae Maeve, Aedion and Lysandra struggle to defend Terrasen, Chaol, Manon, and Dorian face their own fates, and Rowan seeks his captured wife and queen.
