Artificial Gravity: The Alex Cave Series Book 4

By James M Corkill

An impossible gravity surge. A hidden device beneath Iceland's frozen volcanoes. A gold asteroid racing toward Earth.

Former CIA operative Alex Cave is the only man standing between humanity and extinction - if he survives the descent into the mountain that should kill him.

Cave and his team confront a breathtaking revelation: a gravity-manipulating device left behind by an advanced civilization predating human history. But they're not alone. Treasure-hunter Sloan is determined to steal the technology - even if it means betraying everyone trapped inside the deadly tunnel. As shifting gravitational fields hurl characters into moments of catastrophic peril, the story expands into a global-and ultimately interplanetary-race against time when a massive gold asteroid is discovered on a collision course with Earth. To stop it, Alex must take a stolen spaceship from Area 51 into space, risk an impossible landing, and anchor the gravity device to the asteroid before time runs out. But each second brings Earth closer to annihilation... and someone close to him won't make it back.

Fans of A.G. Riddle, Andy Weir, Douglas Preston, James Rollins, and the late Michael Crichton will enjoy this gripping, imaginative thriller from the first page to its explosive, unforgettable finale.
