The Underground by Jerry B. Jenkins is the 6th book in the left behind books. The kids have an excellant idea of how to spread the truth when the schools band any talk about God.
A newspaper! So that's what they do. But the teachers start confiscating copies. They even bring in the police. Two boys at the school, John and Mark, agree to help. Shelly, Vicki's friend, decides she wants to become a Christian too. But when Shelly's mom tells on Vicki, the whole group may be sent to jail.
This book shows how alot of schools react to Christianity. I have heard of schools where people can do anything religious, but when a Christian comes along and carries a Bible around school they get suspended. These books are written well and really do make you think. People can't expect other people to just give their lives to Christ just because you talk to them, and some people think they are safe if they die because they act good or they think God is to nice to not let anyone enter into Heaven. Like when Shelly told Vicki she just wanted to die, even though she wasn't saved she thought she had a good chance of going to Heaven. She didn't understand anything abouut praying, which is why she called Vicki before she O.D. on pills. If Vicki hadn't been there, Shelly would have died and went to an unfriendly place.
