John Hopkins has done a variety of work over the last several decades. Favorite among it was as a college Astronomy Tutor. History, Science and the History of Science have been passions for all of that time. That passion for history has led to scrupulous attention to detail in the historical background when the story is unfolding on Earth. The passion for science has led to the science in the story being based on established published science. Mr. Hopkins lives in Santa Rosa, CA with his wife of 38 years.
