After reading Divergent in one sitting, I could not wait for Insurgent. However, this one wasn't as smooth and gripping as the first in the series. Divergent was a journey, while Insurgent seemed to be more of a bumpy ride with some touch and go moments. There were parts that I struggled over, but there were parts I still enjoyed. Overall, this is still a really good book, and I am still planning on reading Allegiant and Four soon. 
 If you would like to know more about what I struggled with about the book, click below, but be warned: there is spoilers. If you have already read the book, it's no biggie, but if you haven't, I would suggest not reading it. 
 (view spoiler)[ As I said above, Insurgent had its good and bad moments, kind of hit and miss so to speak. Some of the misses for me were: The plot seemed to drag out slowly rather than play out smoothly. There were times where it felt like Roth was info dumping too much tech jargon. I understand in some spots it was necessary. Tris. Okay, you shot Will. I get it. I understand everyone has fears, and that it made her feel guilty, but it honestly took her too long to get over her fear of guns. (I actually don't believe it fully resolved.) I understand why she was upset, but it seemed in every chapter there was a part about her inner struggle over it, and it never fully concluded. Maybe it will in the next book. Along with the story being on a rolling hill, so was Tris and Four's relationship. It honestly got annoying. Fight, kiss, make-up, repeat repeat. I just wanted to throw a cold bucket of water on them and tell them to get their butts moving with the program. My last setback was that I saw the ending coming a million miles away. It was very predictable, and sometimes I would rather be surprised. However that's a fault of my own, I believe. The end was still rather satisfying, to see the factionless turn on everyone but yet Tris still prevailed in succeeding in her mission to release the data the Erudite were trying to hide.

 Even with a few minor setbacks, I still gave Insurgent 3/5 stars. (Maybe a 3.5) I would still definitely say that the series is worth a read, even if this second book isn't quite as good as the first.
