Paul Mark Tag worked for the Naval Research Laboratory as a research scientist for over thirty years before leaving his job to write fiction fulltime. In early 2001, when he made his career change permanent, he spent a year writing short stories only. These stories have been published in StoryBytes, Potpourri, Green’s Magazine, and The Storyteller. In 2005, Mr. Tag self-published his first thriller, Category 5, which took advantage of his knowledge of meteorology and weather modification. Prophecy and White Thaw: The Helheim Conspiracy, sequels, followed.
