O Jerusalem offers adventure, travel, and mystery. This modern fiction depicts its characters' minds. It expresses the anger that most people feel with extremism. The story begins soon after the 9/11 bombings. Christians, Jews, Muslims, atheists and anarchists all risk destroying themselves and each other. Fanatics almost cause an apocalypse. Fake news deludes everyone. In London, Jack is a fanatical atheist seen through the eyes of his moderate girlfriend Emma, whose uncle is the Archbishop of Canterbury. In New York, Chaim is a Jewish extremist observed by graduate student Helen and her Professor. In Istanbul, Sheikh Abu, who directs Islamic terrorists, is studied by Ersan, a Turkish philosopher. In Wichita, Kansas, young Betsey is inspired by the radio preacher Rev. Jones to undertake a Christian mission to Kabul; a cub reporter follows her misadventure. In Jerusalem, a magical Indian child appears and is killed delivering his message, "Make peace or die." The Lollypop minister is a nut-case Israeli populist willing to risk nuclear war. Edward, a sane Israeli, is trying to reconcile Jews and Muslims. The darkroom anarchists, funded by an unknown billionaire, have great technical resources and considerable imagination to cause much trouble.
