Along the coast of the Pacific Northwest lurks a fault known as the Cascadia Subduction Zone. For years, scientists believed the fault to be seismically quiet and no threat to ignite a major earthquake. Only recently have they discovered they were wrong. Cascadia, they now know, has triggered massive quakes and deadly tsunamis in the past, and will do so again. In fact, the next event will be the worst natural disaster in U. S. history, something Northwesterners and the nation are ill-prepared for.

Dr. Rob Elwood, a respected geologist, has studied the Cascadia Subduction Zone for years. Now he’s having repeated nightmares that the subduction zone is about to rupture, that a cataclysm is imminent. Knowing he’s placing his reputation and career at risk, he goes public with his premonitions.

His warnings are met with derision and ridicule, and Rob fears he’s lost all. In a stunning turnabout, however, it’s not his career he must struggle to save, but his life and the lives of those around him.

Rob’s story becomes intertwined with others–a retired fighter pilot attempting to make amends with a woman he jilted twenty-five years earlier and a quixotic retiree searching for legendary buried treasure in the rugged coastal mountains of Oregon.

All are about to live Rob’s nightmare.

The result is a heart-pounding, heart-rending drama set in the Great Northwest.
