Insurgent, the second book in the Divergent Trilogy by Veronica Roth, continues to follow Tris. She and her friends have survived the events in the first book and are trying to figure out how deal with what happened and what to do next. Tris travels with Four, Christina, Caleb, and Marcus to see if they can get aid from Amity. Before they can really get what they wanted they are forced to run from the Dauntless and Erudite traitors who are looking for them. While fleeing they find themselves in an unexpected meeting with a spokesperson from the factionless, those who were cast out of or did not belong with any faction. She wants Four to convince what is left of Dauntless to join with the factionless. The group spends some time with the factionless, and learns more about them including that their numbers are great. The group breaks up to go different ways. Tris and Four continue on to Candor headquarters, where they are arrested and interrogated while under the Candor truth serum. No one can lie while under the effects of the serum, and Tris and Four share some things they would rather have kept to themselves. The power struggles from the first book result in breaks in faction in this book. Does one follow Jeanine's Erudite leadership, or do they follow their own faction? We watch Tris make her choices and follow the path she believes is the right one, and all the things that happen as a result of those choices. There are so many things you learn in this book, it's really hard not to give anything away.
I enjoyed that Tris grew stronger, and more confident in herself. I didn't always agree with the choices she made but I respected that once she made the choice she followed through with it. Relationships, intimate and peer, seem like a really hard thing for her to let happen so it was nice to see some of that development continue. I look forward to her continued journey in the last book.
