Heir of Fire, Sarah J. Maas



and broken, Celaena Sardothien’s only thought is to avenge the savage
death of her dearest friend: as the King of Adarlan’s Assassin, she is
bound to serve this tyrant, but he will pay for what he did. Any hope
Celaena has of destroying the king lies in answers to be found in
Wendlyn. Sacrificing his future, Chaol, the Captain of the King’s Guard,
has sent Celaena there to protect her, but her darkest demons lay in
that same place. 

If she can overcome them, she will be Adarlan’s biggest threat – and his own toughest enemy.
