I've seen quite a few Christian books aimed at teenage girls or for parents trying to raise Christian girls. In fact, the author has written two such titles: Your Girl (aimed at parents) and Teen Virtue (aimed at the girls themselves). However, I haven't seen many such books that focus on boys. It's almost like the world either thinks that religion and spirituality are the domain of the woman or that there are no Christian boys (like they all suddenly become born again after college or something).
Your Boy finally fills that much needed niche. This book takes on a rational tone fully realizing the immense peer and culture pressure that teenage boys are under. Nonetheless, the author makes it very clear that such expectations are not a free pass to participate in activities or act in a manner that does not fit with the boy's Christian values and morals. Moreover, the author suggests that personal responsibility and independence are the keys to a teenage boy growing into a responsible, respectable, Godly man.
