The plot is really fast paced making it an easy read.
The concept is interesting, if not entirely believable.
I went between "the book is amazing" being catch by the emotional part of the story,
feeling as would I be one of the characters to "does this make any sense?" ...
There is so much action that you don't have the time to stop and think about it.
I found problematic the use of serums and simulations with no explanation about how and how long it works,
the division into factions, the faction less people and other things...
As I could switch my rational part off and just enjoy the action I couldn't stop to read it.
I imagined that all of this happens in another world where this all could make sense and that all this "human beings" in the story are not like
"human beings" on Earth.
I give it 4 stars because there is something...something that makes you keep reading and ignore your mind or questions
Maybe there is a kind of serum between the lines that makes you flip the pages in a reading frenzy.
