In post-apocalyptic Chicago, people are divided into five factions, each based on the opposite of what that faction believes destroyed humanity. Beatrice is born and raised in Abegnation, but when it comes time for her aptitude test, she splits evenly across three factions, making her Divergent. She chooses to leave her family and join Dauntless, getting swept up in a mess of politics and a power grab that could leave everyone she knows dead--or worse. 
 I inhaled this book. If I hadn't had to get up the next morning, I would have finished it within hours of buying it. As it was, I neglected studying for a major test in order to finish reading. 
 Brilliantly paced, brilliantly characterized, with a deep understanding of human psychology, this book is easily just as good as The Hunger Games (which I also loved), and if what I'm hearing about Insurgent is anywhere near true, this trilogy may well rival that one.
