I liked this book, it started slow, but got the hang of it after page 100. 
 I could not give this book 4/5 stars, because there were too much little things that I did not like. 
 1. The thoughts of Elias and Laia, for example. Those cursive words that are supposed to be their thoughts. To my opinion they were thinking unlogical/childish things, and it did not add something to the story. 
 2. The way Elias and Helene develop their relationship, from loving to hating, to breaking their friendship and getting back together and that over and over again. It started getting annoying. 
 3. Laia is just played with by Mazen. He keeps breaking his word and she keeps just doing more dangerous stuff, without asking further questions or getting mad or even squeak! 
 4. The ending was a bitt dissapointing, in some way. Can't explain how or why, just felt that way. 
 Good parts: 
 The characters in this book were awesome, each character had someting in their personality that really added to the story. The personalities is what made this book so awesome. This in combination with Blackcliff and the cruel world/situation this book is in, makes it a great set-up. Also liked that Sabaa is not afraid to kill some of the secondary characters. 
 The double love-triangle! Elias and Laia both are stuck between feelings for each other and another person. I don't even know wich ship I like most! 
 Liked the way the story is told by Elias and Laia, 2 totally different people who meet up and intertwine their lives. 
 Will read #2!
