Query: Gem of a book

Awesome book, a real eye opener. It's unbelievable how we're constantly being manipulated by those who have an anti-life, anti-family agenda. The book is well-researched, well written and provides a nice counteract to those who promote garbage in our world. Buy this book, for you and your family, and be stronger for it!
