In the near future, Dr Holland, a scientist running from a painful past, joins the Mars colonisation effort, cataloguing the remnants of Mars' biosphere before it is swept away by the terraforming programme.When an artefact is discovered deep in the caverns of the red planet, the company Holland works for interferes, leading to tragedy. The consequences ripple throughout time, affecting Holland's present, the distant days of Yoechakenon, and the eras that bridge the aeons between.
