Things along America's southern border are rapidly reaching the boiling point. American girls are being snatched from their homes, ranches are burning, and the number of deadly confrontations along the Mexican boarder grows daily.

At night, armed Mexican troops cross the border at will in support of narcotics smugglers and illegal immigrants. By day, Americans take up arms and plan reprisals. An all-out border war is no longer inconceivable. It's happening!

On assignment for the British Secret Service, a man leads a mysterious expedition into the heart of darkness. Sailing up the furthest reaches of the Amazon River, he is captured by a brutal tribe of indigenous cannibals.

Their goal: a vicious jihad that will unite one continent...and destroy another. They possess weapons only dreamed of by the Western allies. Somehow he must escape his captors and live to tell his tale.

With tensions on its southern border threatening to ignite into war, America must look to the one man who might be able to confront the demons in the jungle...and destroy them.
