Meanwhile, an American-born jihadist detonates a suicide bomb inside a Manhattan synagogue. A harrowing question links the violent crimes: Is there any defense for a killer who believes that committing murder is God s will?

They must find an assassin known only as The Sheik before he orchestrates a bloody massacre that could devastate the country forever."
