One thing that Insurgent kept shoveling out nonstop was action, tension, and anticipation. There was never a dull moment while reading and that's how I enjoy my books. During the beginning of the book, because of my lack of information towards what was really going on from the previous novel, I had my moments of start-stop reading and tended to put the book down after each individual chapter. But after I started to learn and remember who was who and what was what, the story picked up for me and I found myself loving the dystopian setting once more.
Tris, the mighty sixteen-year-old girl that she is, started to have some irksome characteristics about her. She's headstrong and brash when it comes to the dangerous and life-threatening, constantly arguing with Four. But there is some growth within her character and we can see how Divergence really breaks her personality into the three factions she has aptitude for: Abnegation, Dauntless, and Erudite. Though Tris did irk me, I found her a strong, courageous, and reliable girl and that made her a kickass character in my book.
One thing I'm sure many people had said after reading the book was possibly along the lines of this: "HOLY COW WHAT?! WHAT IS LIFE? DID THAT REALLY JUST HAPPEN? THE ENDING! THAT ENDING! OH MY GOD, PRAISE VERONICA ROTH ON HIGH!" And I couldn't agree more because those were literally the very words coming out of my mouth. The ending exploded in my face as has me dying to read book 3.
Final Summation: The beginning failed to really captivate me and left me frazzled until chapters upon chapters into the book. If you don't remember what happened in Divergent or who anyone was, I highly suggest a reread because it would be most helpful in remembering the characters and the lead up into Insurgent. And trust me, Insurgent is worth the read, the whole 525 pages because that ending made my head clock all the way around. Book three please come out sooner!
