James Swagger was first introduced to topical science writing for a historical mysteries magazine in Ireland. He trained as a Systems Analyst in the energy industry and has a Masters degree in engineering, a Bachelors degree in Physics with astronomy, and a Masters degree in Science, Research and Society. Initially James Swagger sought out the megalithic monuments of Western Europe in his spare time traveling around the UK, Ireland, and Denmark. His embrace of a multidisciplinary approach to the research of megalithic sites, and the larger view of 'passage grave cosmology' produced his first book The Newgrange Sirius Mystery. He also hosts his own internet radio show called Capricorn Radio, which explores historical mysteries.
