The Hegira is the finest super-sub that Arab oil money can buy. But the U.S. Navy is only now learning just how good this undersea sword of Islam is. Already one American sub has been destroyed, and another crippled, as the Hegira breaks out of the Mediterranean and heads toward America to deliver its lethal payload.

Now it's up to Captain Michael Pacino and the USS Seawolf to find the enemy sub and destroy it?in the ultimate battle between the most advanced weapons technology on the planet...and the sheer force of human courage.
