A pilot races through the sky to stop a nuclear catastrophe in this "compelling" thriller by the New York Times-bestselling author of Pandora's Clock (People). Vivian Henry hasn't heard her ex-husband's voice in three years, but it still fills her with fear. Dangerous and brilliant, Dr. Rogers Henry is calling because he's dying. He offers Vivian a fortune in insurance money if she'll carry out one final task for him: Take the Medusa device to Washington, DC. The Medusa is his life's work--a thermonuclear bomb capable of knocking out all modern technology in the country--and he wants her to deliver it to the Pentagon before it falls into the wrong hands.   Cargo plane captain Scott McKay is miles above the ground when the Medusa begins to speak. A recording of Dr. Henry's voice announces that the device is active and about to explode. With nowhere to land, Captain McKay must rely on his instincts and fly like he has never flown before to prevent a worldwide apocalypse.   Medusa's Child proves once again that John Nance is the "king of the modern-day aviation thriller" (Publishers Weekly).
