This novel can be described as a stand-alone follow-up story to my previous series on the Time Patrol and Nancy Laplante and is a sequel to one of the chapters contained in my novel CHILDREN OF TIME, which described the rescue of two young Neanderthal children by the Time Patrol in 50,000 B.C. The letters ‘A’, ‘B’ and ‘C’ following the year in dates denote in which of the three parallel timelines described in this series the action is happening, with ‘A’ denoting the original timeline of Humanity.
