Want to be an effective parent? Here's a mom with a lot of inspiration.

My friend, a reporter based in the Annapolis area, recently told me about a mom she had interviewed for a feature story. This mom of grown children is and has done it all. She has a syndicated one-minute radio series called "Front Porch Parenting" (available on  her website), more than 40 books published with over 2 million copies sold, and an informative blog. She is a sought after speaker and consultant. I've been reading through her blog and am enjoying it as well as the radio program. Now, I need to get some of her books for my boys.  Note, her work has a christian-based theme. Anyone read her books? Recommendations?
