I didn't enjoy Insurgent as much as Divergent as it took me a bit longer to get into it but as it came closer to the end I couldn't put the book down. I jumped to grab Allegiant once I closed the cover and I have it ready to go once I finish writing this. 
 The ending is somewhat of a cliffhanger. Not something that leaves you going "No! Whats going to happen!" but leaves you knowing shit is going to hit the fan. 
 I like how even though the heroine is in a romantic relationship the book is not based around it. We see few moments where Tris and Four interact. They seem to work more independently and it is great to see for a YA book that a girl doesn't need to rely on a strong boy or a relationship to get by in life. Their is not a strong focus on the romance and its a great change to see. 
 I also really liked how our heroine isn't always strong. It seems Tris has some PTSD and it wasn't shied away from. We get to see her scared but being brave and concurring those fears. 
 One thing that bothered me was that I kept getting a little confused. At one stage I thought it was said that Amity was beyond the wall and that made no sense to me as nobody can get past the wall without their being Dauntless guards to stop them. 
 But the question about whats beyond the wall... I figured that out watching the movie before I read the book. So I gave myself a little pat on the back for being right :D 
 Two things I took away from this book that I didn't for any other YA I have read is: 
 1) It's ok to be strong and brave by yourself and to not rely on others, 
 2) And, It's ok to be weak and scared and to rely on other to pick you up or help you carry on. 
 "Do remember, though, that sometimes the people you oppress become mightier than you would like."
