This is the third instalment in the Throne of Glass series and takes place directly after the events that occur in Crown of Midnight. 
 Celeana has travelled to Wendlyn, with safe passage granted from once-friend and so much more, Chaol. Here, the reader learns of her past as Celeana hones the skills to aid her future. With instruction from fae warrior, Rowan, she learns all she needs to avenge the brutal murder of her friends but also how to shed the walls she has built around her heart. 
 Dorian and Chaol remain ensconced inside the glass castle. Their thoughts never stray far from the assassin that once claimed their hearts but they too must cast their gaze further afield, and once again unite, if they have any hopes of protecting their home from the evil that is amassing. 
 I think my four star rating reflects how utter trash I am for anything Sarah J. Maas, rather than my overall enjoyment of this. I found some of the initial sections too slow-paced and confusing and it was only, really, the last 100 or so pages that brought this entire thing together. This thrice-split perspective felt a little overwhelming, during the initial stages of the novel, and I constantly struggled to find my place and to order the events that were taking place. Also, I found the pacing to be rather inconsistent, with some sections of little forward motion and others seeming full of new facts and faces I was, then, unprepared to face. 
 I adore these characters and Celeana especially has captured my heart. I believe that if it wasn't for such a strong bond already formed with this cast, and seeing how much Celeana's character arced throughout this narrative, my rating would have been three stars, at best. I'm still enamoured with this world, but this has to be my least favourite series instalment.
