One-hundred feet below the surface of the frozen Ross Sea, crushed between 200 feet of glacial ice and volcanic rock, lies the remains of an ancient flying saucer and the unidentifiable remains of its luckless pilot. U.S. Navy divers have been tasked in a top secret mission to extract information from that crash site. In this third and final book of the Jason Parker Trilogy, government scientists Jason Parker and Laura Smith join forces with an investigative reporter, a blind remote viewer, an Osage Marine from the Oklahoma Tzu Washtaki clan, a synesthete cosmologist, and a Troll named Truman to save the world. In the midst of threats and squabbles between the U.S. and China, and conflicts both on and off planet, world survival concerns remain hidden. On Mars and its moons, Earth’s Polar Regions, and the deep sea off Taiwan and the U.S. East coast, the light side and dark side of U.S. Intelligence competes to gain advantage in a world where insidious genetic warfare may hold the upper hand. But like swords and plowshares, there are two sides to human genetics. In the right hands, it might be the solution to saving mankind. When the cosmos strikes Earth with a fatal blow, will salvation come in time? "Kudos to John Clarke for coming up with a science fiction novel that defies the imagination but feels so very real." -- Readers' Favorite "...A race against time to save humanity not from the alien threat, but from itself. ...Atmosphere is an accomplished work which places humanity at the center of the science fiction concept, and is a highly recommended read for serious fans of the genre." - K.C. Finn, award winning author "It's a satisfying trip for the mind that ... nicely blends blazing adventure sci-fi with the more thoughtful, speculative variety pondering humankind's destiny. An engaging wrap-up to a sci-fi series that manages to be apocalyptic, upbeat, intelligent,and pro-U.S. military."--Kirkus Reviews Clarke's ingenious solution to continuing the human species---will leave you astonished and breathless. He leaves the dooropen for further tales in this fascinating hard science fiction universe. The Jason Parker Trilogy consisting of Middle Waters , Triangle , and Atmosphere, is top notch hard science fiction wellworth your time. ---- Robert G. Williscroft, Author of The Starchild Trilogy "Atmosphere is author John Clarke at his best - writing authoritatively about science in a compelling narrative that weaves what we know with that which we are on the verge of knowing. In this, the final installment of the Jason Parker trilogy, Clarke gives us the third act of an end-of-the-world saga in which the question is not just survival, but transcendence; at stake is the next step forward in human evolution. Clarke has tackled one of the biggest challenges facing a writer of science fiction - what is there new and surprising to say about the end of the world? - and succeeds brilliantly." ----- Max McCoy, award-winning author and journalist. and writer of four licensed Indiana Jones adventures for Bantam.
