Lost Oasis: Zack Tolliver, FBI, Book 8 (Unabridged‪)‬

Modern science and high technology come up against deeply rooted Native American cultures and ancient rituals in this Zack Tolliver, FBI, story, where the Goblin rocks and barren flats of Joshua Tree National Park surround the rugged Eagle Mountains. 

A world-class scientist goes missing while consulting on a high-stakes project, the construction of an electric storage battery in the deserted pits of the old Kaiser Iron mines. Did this eccentric world-renown hydrologist simply wander off? Or was his fate more ominous? 

FBI Supervisory Agent Janice Hooper assigns Zack Tolliver, FBI, to the investigation. When someone plants a bomb in his Jeep the day he arrives, Zack realizes there is more at stake than anyone knew. Soon, he finds himself in a desperate duel with an unknown assassin who may very well be more than his match.
