TCOM1 was written for the most part while the author was traveling and working in the Canadian Arctic during 2006-2011 and has been edited often since then (as recently as 2018) to keep abreast of developments in the exploration of Mars and to 'fix' some story lines (George Lucas did it!). The author's experiences as a technician, technologist, Military Officer, Project Manager and late-to-the fold Pink Floyd/Roger Waters and melodic techno music fan have greatly influenced the two TCOM books. He is still a consultant to the Defense Communications Industry and still travels frequently to the Canadian Arctic, in all seasons.
TCOM2 continues the story of Sam Aiken on Mars. It was written between 2011 and 2018 and underwent many changes in that time that made it less in the style of TCOM1 and turned it into something else. Maybe after he's read it fifty or so times the author will understand it. It does answer many of the questions left unanswered in TCOM1 (some intentionally, some not) but it is not the same in terms of pacing and the attempt to mimic classic sci-fi of the nineteen thirties, forties and fifties (although there is some of that too). Music influenced the writing of TCOM1 in some ways, mostly subtly. Music is present in TCOM2, for a different reason.
