Query: Cool premise, but only an okay book

This book about two teens caught in a cult like the one in Waco has a very cool premise, but I never really believed in it. First of all, the guy and the girl didn't talk like any teenagers that I know, but more like grown-ups think that teens talk. Second, there were too many things that were impossible. The leader of the cult banned TV, but not computers. There was a guy from the FBI inside the cult, but he he did not talk to FBI headquarters as soon as he saw all the guns in the cult, and he did not even have a backup cellphone? Plus, after all the bloodshed at the end, the guy and the girl do not seem very affected by their experience. Too many holes in the story for me to really enjoy it.
