When a mysterious explosion destroys his research vessel in search of a lost river, Alex Hawke is captured by indigenous cannibals and enslaved deep within the Amazonian jungle. Before he escapes, he learns that a fearsome foe is preparing for war - but against whom? When he regains contact with his American and British intelligence counterparts, Alex's worst fears are confirmed. The men in the jungle are highly trained Hezbollah warriors who are planning an unspeakably violent jihad against the United States. While the U.S. focuses its efforts on the escalating border disputes with Mexico, Alex takes on the task to put a stop to the deadly plot.
