3 1/2 stars. I read this on the recommendation of my daughter. YA but entertaining. I wish though the author went a little bit more into what led up to the different factions, and how it was decided on these five factions (dauntless, abnegation, erudite, candor and amity) and no others. And we never got to find out what it is the dauntless were tasked to protect the city from...what was so dangerous outside the walls (or maybe it was really what was inside the walls that they needed to protect against and they just didn't do a very good job of it). I suppose though this is what the other books in the series (trilogy?) will accomplish. I did like the character of Tris/Beatrice and liked how the story progressed through her point of view. Roth managed to convey in a compelling way Tris' thought processes and the how and the why behind how she came to her sometimes very hard decisions. Not quite as gut-wrenching as some of the scenes in The Hunger Games but well worth the read.
