A late twenty-first century time traveler battles bards, druids, warrior queens, and Roman cohorts for survival during the Celtic rebellion against the Romans in Britannia, 60 AD. Time traveler John Moore's fate is determined by four women: the Celtic warrior queen Boudicca; Tailtu, a gentle slave purchased from another clan; Dr. Eleanor Roberts, a severe, jealous and brilliant woman who spearheads the time travel mission; and enigmatic Dr. Cheyenne L'Esperance, herself a time traveler from an even more distant future. Moore's mission to survive three battles against the Roman legions coincides with survival tactics and backstabbing in the modern government department. The savage past clashes swords with the desperate future in a time continuum of treachery.
