David McKoy (may he rest in peace) served in the US Navy. In civilian life, he utilized his skills to protect and serve civilians in many different capacities. His knowledge of personal and professional security as well as military history and weapons figure prominently throughout the Call Sign: Wrecking Crew series.
Lynn Hallbrooks has loved the idea of writing since her childhood but never considered it seriously until after serving in the military (USAF) and working in hospitals was no longer a viable option.
When she isn't writing, she is helping others especially fellow authors.
