Why my book is needed

Enclosed is a response from a government individual after sending him a note on the book last night. “...As a side note, I'm sitting in a class on Information Assurance and one of the student’s works for a company using SCADA and he was recently told they are going to merge their corporate network with the SCADA network. He said they are looking for their IT shop to lead the security team to identify and solve the problems. I told him what you've said and wished him the best of luck. Maybe I should recommend your book!”
