Amid the Canary Islands lies the massive crater of the volcano Cumbre Vieja. Scientists theorize that one day the volcano will erupt, triggering a series of events that would lead to a tsunami wave higher than any in recorded history. This mega-tsunami, with waves of more than 150 feet in height, would ravage Europe, Africa, and ultimately the East Coast of the United States, causing immeasurable loss of life and destruction ...

It is discovered that Ravi Rashood -- America's nemesis, the former SAS officer who is now the head of Hamas -- has hatched a diabolical plot against the West: to fire a nuclear-headed guided cruise missile -- Scimitar SL-2, named for the curved sword of the Muslim warrior Saladin -- into Cumbre Vieja.

United States Admiral Arnold Morgan, the retired National Security Adviser, knows something worse is to come after Rashood explodes Mount St. Helens. But stopping him won't be easy.

As the terrorists' deadline approaches, Morgan and his team must consider the unthinkable and assume the daunting task of organizing the mass relocation of major population centers along the East Coast to safer ground.

Morgan finds himself battling his greatest enemy yet, racing against time to locate Rashood, the silent, underwater marauder, and stop him before the unimaginable occurs.
