Not exactly the kind of book you expect your pastor to recommend to the general congregation, but it was a good look into... it's... topic. :-) Amanda and I (or mostly I) keep looking for a Christian-worldview-based book like this to address one topic in particular that concerns/interests us, but still didn't find it here. But plenty of good tips and other information.
