I love fantasy, especially if a map comes with the book, because I love to follow the journey of the characters on the map and I also love maps in general and like to look at them and imagine how the fictional world works. I was also psyched about the story of these two processes who fall in love with each other. I thought the idea was original and rare. So, I had high expectations about "Of Fire and Stars". 
 I liked the world the author built but I felt that it was not really detailed. The religion of the Six and the different kingdoms and the use of magic was not at all elaborated. I found the world a bit contradictory as well. The story depicted a world where gender did not matter in relationships. So, one might assume that the world is not heteronormative. But this was compromised by how the kingdom of Mynaria worked. The throne was always given to male members of the royal family even if there was a girl first in line for the throne (Mare, one of our princesses). Also, the way they treated Denna, the other protagonist princess, was not really free from gender related judgement. Denna had to go to tea-parties and making small talk while the kingdom had serious problems to face. 
 So, I was disappointed in two ways. One was about the pour world building and the other was about not really feeling the gender-neutral ambiance my two great initial expectations. 
 Also, the characters did not really have depth to them to care enough about their hardship or their death. The plots were weak and repetitive. And the real "villain" was very predictable. 
 I was surprised only once or twice by plot twists. So, all and all, I enjoyed small parts of the book and the idea about a different gender-neutral society and the magic in it. But it was not complex and captivating enough to give this book more than two stars.
