It is no secret that I am a fan of Sarah J. Maas and so it is needless to say that I have been waiting to get my hands on this book for about a year. 
 The book picks up shortly after where A Court of Mist and Fury left off. Feyre is now in the spring court, spying on them to try and find out what the King of Hybern is planning. She utilizes her time pretty well in the Spring court and love her revenge against Ianthe. From the naive little girl that she was in the first book, Feyre has come a long way to manipulating Tamlin and the Spring Court in the way she did it. Then her journey takes her back to the Night Court and into the war. Now here's where I had a small little problem. For people who knew that Hybern could attack any moment, they spent an awful amount of time dawdling. I don't know why anyone would wait twelve days for a meeting (gathering of the High Lords) when the King of Hybern already has the cauldron and could attack at any moment. For a war that could break out any moment, people seemed awfully laid back and lacked the sense of emergency at the beginning that usually comes with a war. 
 The first thing that I liked about the book was Feyre's development. She seemed more in control of her life and her destiny. The cursebreaker finally lives up to the expectation that we usually have from a protagonist. Looking back, she has really developed a lot over the three books and though it was a bit tedious towards the beginning, it was worth the wait to see her transformation. Rhysand's character though was bit underplayed in this book to give Feyre the full attention. He is supposed to be the most powerful High Lord in the history of Fae, yet we are only told that he 'fought' with everything. I wish we had been able to see more of Rhysand in action on the battlefield. Azriel, Cassian and Mor lived up to their names. I loved Mor in action in the Summer Court. And OMG! Amren... yes, we see her true form in this book and that is all I am going to say about this character. 
 I loved the diversity of characters in the book. A High Lord who is Bi-Sexual, and a major character confessing to like people of the same sex (I am saying it this way so as not to give a spoiler on who that character is) brings in some diversity that is much needed to be normalized. 
 The climax was awesome, except for Feyre's dad's part. That felt too much like a Bollywood twist to me - Prince of Merchants! Also, I am glad the closure that the author gave to Feyre and Tamlin's relationship. 
 Over all it was a complete page-turner.
