Walter and his assistant AJ, struggle to keep up with the demands for spatial information needed by the US Military and intelligence agencies. They are observes for the National Geo-Spatial Intelligence Agency and are often called 'the map makers'. But their presence on the ground often changes their job description and they become the point of the spear, acting on the intelligence they were sent to collect. Their services are in demand to support the rescue and recovery operations after natural disasters and to combat threats from Somali pirates and Jihad extremists in Indonesia. The author has also published a series: A Code Named Walter, and the book The Passage.
