Jerusalem: where earth meets heaven, home to seekers and heretics, hustlers and madmen, dreamers and the faithful of every persuasion. In this holiest and most fractious city, where religion and politics are inextricably bound, a plot unfolds to bomb the sacred Temple Mount.

Christopher Lucas, an expatriate American journalist, skeptical and searching, stumbles upon the Temple Mount plot while on assignment to investigate religious fanatics. Unwittingly entangled in the bombing plan is another American, Sonia Barnes, a Sufi convert and nightclub singer, who is drawn with Lucas into the dangerous intrigues surrounding the Old City.

They encounter Adam De Kuff, an unstable Jewish guru; Raziel Melker, a strung-out Kabbalist who foists De Kuff into the role of messiah; and Jan Zimmer, a soldier of fortune routinely at the center of the world's flashpoints.
