These books by Veronica Roth have a lot of parallels to JWs and cult control.
I think Veronica Roth (the author of the series) has a JW background. Wikipedia says the following:
"Her maternal grandparents were concentration camp survivors, whose religious convictions pushed her mother away from religion."
In the second book of the series Tris is somehow looking at a religious ceremony and then thinking of her own upbringing.
Tris remembers the religion of her parents and admits that one part of her still holds on to this faith and another just finds it ridiculous - "the prayers before meals, the weekly meetings, the services, the poems about a selfless god."
Then they invite Tris to a religious ceremony, they give her a hand, talk about God's peace which is undeserved. She frees herself and runs as fast as she can to the trees. She stops and is fighting with tears.
