Three main narrative threads are spun into the yarn that is “People Not Seen”.
The first and primary thread follows the art student Dirk as he arrives in Iceland and embarks on his quest for finding the fabled Hidden People. Dirk travels through the country and talks to seers, psychiatrists and hackers about the Elf phenomenon.
Most of the interviews, though, are with eye witnesses who have had first hand experiences with the invisible people. Some have only seen them from afar, others were invited into their rock dwellings.
In the last chapter of the book, all three threads are spun together to form the end of the story.
