The year is 2130. The first-ever expedition is sent to Mercury to search for the cause of an unknown source of electromagnetic radiation that can destroy spaceships passing by the planet. Thought to be inhospitable and lifeless, the surface of Mercury provides startling surprises for the crew that endanger their lives and challenge their established notions of what it means to be a sentient being. And some of the crew members have their own separate agendas. The scientific appendix introduces listeners to the wondrous world of Mercury and how it has been portrayed in literary fiction up to the present time. The author then uses scientific literature to present a concept of life that is not based on carbon chemistry or the need for water. There is also a discussion of consciousness based on electromagnetic wave theory.
