Comes the Six Winter Night — James LaFond

The Pillagers of Time chronicles the efforts of a team of time-travelers operating out of the 21st Century on behalf of their 29th Century sponsor. They are tasked with recovering lost genes and genius' from the deep past and are opposed by a cult of 24th Century fanatics. Three-Rivers 16th, Century Iroquois prophet and language savant, now lives in 21st Century America, the world he knows as Sunset. He works as a translator for a genetic reclamation or “time-hunting” unit managed by his adopted mother, a genetically engineered 24th Century assassin who he knows as the Sunset Lady. Three-Rivers and two companions journey 75,000 years into the past, to the eve of the Sumatran Super Eruption in search of the doomed Dawn People who face a world that will soon be shrouded in a six winter night.
