The Stonehenge Rift (The Company Chronicles) (Volume 1)

The year is 1890.  Reginald Radford is a weapons master for a secret organization that works to keep the planet safe from peril.  His latest mission takes him to southern England where initial reports of a threat have radically understated the danger to all life on earth.  Can his hastily assembled team of specialists leverage the technology at their disposal to save the planet?  They will only have one shot. Foreword by Austin Sirkin.
