About the book

This book is an infallible blueprint for dealing with and overcoming any of life’s difficulties. Infallible, yes. It’s contents have been repeatedly put to the test in what would normally be considered insurmountable obstacles that the Brock family faced. 

These obstacles included kidnapping and attempted murder, gross medical malpractice, David’s eight heart attacks, the threat of bankruptcy (sidestepped in the most extraordinary way) and the temporary death of their youngest daughter from a drug overdose. It has almost been a case of you name it and they’ve faced it and overcome it, without lingering consequences or damage. What you are about to read, if acted on, will make you ‘bullet proof’.

The Brock family is proof positive that life’s difficulties need not become life’s tragedies.

This book contains nothing but verifiable facts, witnessed by very credible people. Therefore, there are no opinions expressed.

I’d LOVE to hear from you
