The first man he murdered returns to teach Ash Tarberrn how to be human.
Robin’s latest novel Future Past is set in our dystopian future in a world made by global warming and the ongoing struggles between societies on earth. Genetic engineering has become a habit, cities float upon a burdened polluted sea.
But we of the Free World are losing the battle with the intemperate Followers, an inadmissible conclusion to decades of war. Ash Tarberrn has an answer to the problem, and contrives a virus to  eradicate the Followers.
That takes the reader to the end of the first chapter. What follows involves a question of guilt, the restoration of one man’s humanity, and the terrifying consequences of Ash and his cohort’s attempt to escape their history using time travel.
