What a nice surprise! 
 I heard mixed opinions about this book. Some people thought it was just okay, others didn't like it and some people loved it. So I didn't know what to expect from this book. And to be honest, I was really afraid to compare it to A Court Of Thorns And Roses. So I was apprehensive about this book. 
 It turned out that I really liked it. I loved the world building: this whole dark vibe was really cool, I loved how she described the castle. 
 I also really like the mythology side of this book, I thought it was different and it added an another dimension to the story. 
 Now the characters were also really interesting. I like how the main character, Nyx had that dark side (but not too dark). She is basically everything that I like in main characters. Ignifex was also a great character, I always have a thing for the characters who are not really who you think they are. And he was funny so I couldn't have asked for more. 
 I also liked that this book was really unpredictable, I guessed some parts but overall this book was unpredictable. 
 So yeah I really liked this book, and I'm happy I did.
