Insurgent (Divergent, #2)

One choice can transform you - or it can destroy you.
Tris Prior's initiation day should have been marked by celebration: instead it ended with unspeakable horrors.
Now unrest surges in the factions around her as conflict between their ideologies grows.

In times of war sides must be chosen and secrets will emerge. Tris has already paid a terrible price for survival and is wracked by haunting guilt. But radical new discoveries and shifting relationships mean that she must fully embrace her Divergence - even though she stands to loose everything.
