Here's a bit from his blog:
"This book was a labor of love. As a father with an eighteen year-old daughter, I’ve been thinking about issues of courtship and marriage for a while now. However, I knew that the ‘rules’ I grew up with weren’t going to cut it. This book is the result of my personal journey through God’s word trying to figure out what it means to be a responsible father when it comes to the courtship and marriage of my daughter."
I have not read the book yet but have already ordered it :). You should too.
