Science. Fiction

HYBRIDS, book I is a cerebral cyberpunk thriller that tells the story of a new frontier for the human race, and the man who holds the key to its survival. In the year 2218, mankind has colonized Mars with four expansive cities. Maxwell Tanner, an insomniac and technophobe, laments his monotonous existence until a seemingly random attempt on his life turns his world upside down. Pursuing his would-be killer, Tanner is drawn into the city’s dark underbelly where becomes the centre of a diabolical plot against the human genus. Surrounded by physically-augmented mercenaries and powerful oligarchs who need him silenced, courting murder and espionage at every turn, Tanner stays ahead of his enemies using skills and tenacity he didn’t know he had. Can he win the race to unmask the assassin and expose the biggest conspiracy in recorded history, or will Tanner be swallowed-up by an unforgiving city that’s unable to reconcile its love for science and its hate for mankind?
