Mike Rejest is a dedicated Special Agent for the Bureau of Land Management (BLM) out of Albuquerque, New Mexico. He is responsible for the Southwest region and has over 35 law enforcement officers reporting to him. Over the past year, however, he has detected an ominous trend developing. It appears as if an environmental terrorist may be operating from somewhere in the 4-state territory Rejest oversees. Cattle barons have been executed in the night, corporations suddenly destroyed by unexplained explosions, even the unsolved murder of several of his field operatives and government trappers. Throughout the West a terrible legend is being created - of a ghost rider on a silent horse, coming in the night to deliver swift and exacting punishment. His victims are from all walks of life, all ages, both sexes. So begins the struggle, between an agent of the law and a messenger of retribution. The action spreads through New Mexico, Colorado, Utah and Arizona, covering the last remaining wilderness areas of the Southwest. Battle-lines are drawn and friendships challenged, as the environment takes center stage before the public once again. Finally, frustrated by the failure of everyone else, Rejest gathers his own team of trusted fellow BLM Rangers. They set out to hunt down the stranger in the New Mexico wilds, only to discover that they are being pursued instead. The difference between predator and prey grows murky, only separated by the quickness of reflexes and the caliber of firearms.
