A keen outdoorsman, David Ricciardi incorporated many personal experiences into WARNING LIGHT. He’s backpacked through the mountains of the western United States and Alaska, received extensive training from law-enforcement and US special operations personnel, and once woke up for a 2 AM watch aboard a sailboat only to discover that it was headed the wrong way through the Atlantic sea lanes in heavy weather, with one of the crew suffering from hypothermia. In addition to being an avid sailor, David is also a certified scuba rescue diver and a former ski instructor.
