The book itself was a real page turner. The foreshadowing was way to obvious and annoying, but as a whole it was a pretty enjoyable read. My biggest issue with the book was the very obvious allusions in the story that go completely against my rationale. The holy and selfless group, the Abnegation, are pitted against the intelligentsia group, the Erudite. Science is portrayed as being the bad guy trying to manipulate the world, while the Erudite are the good guys living only to serve others in a selfless, giving manner. These two groups are kind of the backdrop to the story. A third group, the Dauntless, take center stage for the majority of the book. They are the brave. Two other groups, Candor and Amity (honesty and peace), are the final factions, but they don't have much of a part in this book. 
 I won't go into too many details about the book, but I will say this: the writing is fairly good and the story is told at great pace. I had a hard time putting the book down. I disagreed completely with the main theme of the story, though. In my experience, holy groups and religion in general has been responsible for more manipulation, questionable ethics, and murder than science ever will. Science might have given us a weapon, but more often than not, it's god's name that's invoked when those weapons are used. 
 Fair warning: this book is Christian Fiction disguised as a YA book.
