The biggest problem with this book is that the author's theology often gets in the way of her advice. You don't teach teenagers to be careful students of exactly what the Bible says, then turn around and twist passages like Mark 9:1 and say they don't really mean what they say because that makes premillennialism untrue. And although she professes to believe in freewill, her Calvinism also causes her problems. Some of her arguments are just as specious as the ones she is trying to counter from atheists.
On the other hand, this can be used carefully as a guide in talking to your children about the things they will hear at school, on media, and from friends. Several chapters contain a wealth of information that will save you a lot of time gathering for yourself. My husband will in fact use some of it in the high school class he is teaching, but he has a great deal of knowledge gathered over decades and can find his way through the potholes. We also have a son who has a degree in Apologetics to bounce some of these things off of. If you use this book, be sure you use some of the same kind of resources to avoid problems.
