SUGGESTION: Soul Searching & Almost Christian
While these are not exclusively Catholic (there is a whole chapter on Catholic teenagers), these two books are part of the largest study on the spiritual lives of American Teenagers and are a very powerful and enlightening read for anyone who works in ministry. It would be great to have these in Verbum for the reference and to be able to use it as a resource!
