GENRE: Post Apocalyptic, Action
Emotions are completely under control using medicines. This may seem like a good thing but in the hands of the wrong people they could create the perfect killers.
This series has a very steady pace that just makes it easy to read. I suggest getting the whole series at once since you will not want to stop. The characters all seem to hide their own secrets that seem to come out at the most inopportune times. This complexity keeps you guessing throughout the whole series until the end.
