This book is dedicated to Kenneth Marino, the members of Rescue 1,
and all New York City Fire Fighters who lost their lives on and after
September 11, 2001. They made the ultimate sacrifice by giving up
their lives so others could live.
I still remember getting the phone call that Kenny was missing, and
it upset me more than words could describe. Kenny was probably one
of the nicest people I had the privilege of knowing, and he would do
anything to help someone else out. That is probably why being a
fire fighter was one of his dreams.
