It varies. I got the idea for my first book, Where Freedom Reigns, after the tragic shooting at Columbine High School. Sadly, its theme of gun control is still painfully relevant today. The impetus for The Tempest’s Roar came from a long-standing interest in whales and dolphins. When I was a college student, I worked one summer at a salmon cannery in northern British Columbia during which I spent many days out on the ocean watching Orcas breach beside my boat. Later, after I got married, my wife and I loved to spend our summer vacations on Long Beach Island, New Jersey where I would often see pods of Bottlenose dolphins swimming up and down the beach. The idea for The Covenant Within came after a trip to the land of my Viking ancestry on the Orkney Archipelago off the northern tip of Scotland. No Greater Evil resulted from a blending of my experience as a president and CEO and my fascination with national politics. As I mention in my biography, both these two books delve into the workings of the human mind and the thin line that separates imagination and insanity. Finally, Cry Savage Tears, is the product of my deep fascination with the savage innocence of the Siberian tiger, and the cruelty of the poachers that are driving these big cats toward extinction.
