30,000 B.C. Chronicles: Galway

Shipwrecked in the Paleolithic with their modern tools and weapons long turned to dust, survivors of a scientific time travel expedition join their native clan mates on a brutal crossing of the northern ice shelf in search of would-be rescuers from the year 2233. Galway is the fourth book in the 30,000 B.C. Chronicles series. Journeying from the Cliffs of Dover to the coast of Stone Age Ireland, the characters compare the bounty of the wild, prehistoric land against memories of the scorched, used-up Earth they left behind. Their trip is turned upside down by the arrival of the Hunter.
