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.
