Insurgent
By: Veronica Roth
On the day of Tris' initiation into Dauntless, a coup leads to the very thing the establishment of the factions tried to prevent, and the factions find themselves on the brink of war with one another. Now, with Erudite trying to seize control, each faction is splintering into loyalists and traitors, and it's hard to know which is which. Tris has to decide where her loyalties lie while grappling with unrelenting guilt and grief; emotions that affect both her choices and her relationships. With her Divergence fully exposed, Tris is not sure if she is more helpful or harmful to those she loves.
