This is the best practical Christian world-view book for teens I have ever read. It is up-to date, clear, biblically sound, and easy to read. But it is not just for teens - it's helpful for parents too. The authors do an excellent job of explaining the cultural moment our young people are facing, and then they go through a lie-truth-redemption model to explain how to biblically think about each topic. I took a week this summer and read through it with my 3 teen girls. I highly recommend adding it to your must-read list. It would make a great small-group book study for youth groups, christian schools, or families.
