I am delighted to present TUMACÁCORI GOLD, a fiction adventure novel of good verses evil, packed with factual history, mystery, suspense and a touch of romance. Based on the uncanny discovery of a whirlpool vortex on the Colorado River which is rapidly depleting Arizona's precious life-sustaining water, Logan Price, a desert biologist and ghost town adventurer, travels deep into the mystifying labyrinth of the Grand Canyon to locate and destroy the threatening anomaly before the state is turned into another Sahara Desert. Logan's meticulous investigation of the diminishing whitewater rapids unexpectedly leads him to an enchanted, romantic encounter with a beautiful Indian princess, the shocking discovery of a lost, ancient civilization that time has forgotten, a hair-raising journey into a perilous world that lies far beyond the confines of reality, and finally, the amazing discovery of an enormous mountain of gold of untold worth, know as the lost Tumacacori gold. But as Logan unearths the vast fortune in gold, the heroic desert biologist suddenly realizes that the gold isn't the only treasure that lies beneath the dry and cavernous desert as he miraculously turns the desiccated Arizona desert into a garden of Eden.
