The dazzling new novel in the #1 New York Timesâ€“bestselling series from the grand master of adventure. It is called zero point energy, and it really existsâ€”a state of energy contained in all matter everywhere, and thus all but unlimited. Nobody has ever found a way to tap into it, howeverâ€”until one scientist discovers a way. Or at least he thinks he has. The problem is, his machines also cause great earthquakes, even fissures in tectonic plates. One machine is buried deep underground; the other is submerged in a vast ocean trench. If Kurt Austin and Joe Zavala and the rest of the NUMA team arenâ€™t able to find and destroy them, and soon, the world will be on the threshold of a new era of earth tremors and unchecked volcanism. Now, that canâ€™t be good.
