I had so much trouvle getting into this book at first. To be perfectly honest, I think I was trying too hard to draw parallels between this novel and the Throne of Glass books. To be fair, one of the main characters in this book is an assassin for hire just like Celaena in Throne of Glass, not to mention their similar personalities.
That being said, this book stands out all on it's own. It's a story about the Blood Queen and the Sun Queen and the impact they have on thise around them and on their country. In the beginning we don't know which queen is the Sun and Blood Queen, but we find out pretty quickly later on.
Overall, I think the worldbuilding was excellent and the character development was pretty well paced.
Definitely give this book a shot if you've been debating on reading it.
