Zero Hour is the dazzling new novel in the #1 New York Times-bestselling series from the grand master of adventure, Clive Cussler.

A new energy source holds the promise to change the world. If it doesn't kill it first.

It's called zero point energy, and it really exists - a state of energy contained in all matter everywhere, and all but unlimited. Nobody has ever found a way to tap into it, however. 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 submerged in a vast ocean trench. If Kurt Austin, Joe Zavala and the rest of the NUMA team aren't able to find and destroy them - and soon - the world will be on the threshold of a new era of catastrophe and unchecked volcanism.

Clive Cussler, author of recent New York Times bestsellers The Tombs, Poseidon's Arrow, and The Striker brings us the adrenalin-soaked doomsday masterpiece, Zero Hour.
