Zero Hour

Clive Cussler, author of the bestselling Dirk Pitt series, and his co-author, Graham Brown, send hero Kurt Austin into the heart of the storm in the action-packed NUMA Files series.

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

It's called zero point energy - 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 does.

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.
