Insurgent by Veronica Roth is the second of the Divergent books. Tris has left the Dauntless and is now holed up with a bunch of teens who have all left their assigned compounds.
The place where Tris ends up is a multilayer skyscraper — a popular choice for dystopian fiction. I imagined this particular building being like the one Chess find in Port Oro, in The Lost Compass by Joel N. Ross.
Divergent derives its plot from world building. Tris has to pick a different faction than her family to give us a glimpse into more of the world.
Now having taken the Dauntless piece of the world to its extremes, there's nowhere else to go but elsewhere. Unfortunately this second glimpse into post-apocalyptic Chicago isn't as well formed as the first one.
Much of Insurgent is taken up with the the residents of the compound falling under unexpected simulations. If these would be rebels are smart enough to be capable of undoing their society — why are they so easily, and repeatedly fooled? This is more of a case of fool me once, shame on you; fool me twice shame on me. This is upwards of fool me a dozen times, I'm gullible!
