"I believe Mark Twain said, "Truth is stranger than fiction, but it is because Fiction is obliged to stick to possibilities; Truth isn't" McKinnon's writing is based on true experiences and integrates these true events to amaze the reader. A great read with lots of twists. Looking forward to more of McKinnon's adventures."
