Undercover Papist - John Paul 2 High - Book 4
By Christian M. Frank
So you've just been sent on Mission Impossible: to get the most beautiful girl in your school to come back to the Catholic Church.
Brian goes to Bible Camp undercover to rescue Allie, but it seems like a lost cause.
Allie seems to be getting on just fine: helping her new Christian friends love God, and dating the camp's hot worship leader.
But inside, Allie still feels lost, and wonders if she's really changed.
Between figuring out how girls work and defending his faith against zealous fellow campers, Brian starts to realize that if he wants to help Allie, maybe he's the one who needs to change.
