After a short, but devastating nuclear war the face of the Middle East has changed forever. The 'Ingathering' - the world's greatest population transfer - has begun. Huge people groups - from India and Myanmar, Pakistan and Afghanistan; from Nigeria, Zimbabwe and South Africa - and many other parts of the world - are on the move, all travelling towards one destination.

Four young men, who met first in Afghanistan, have been reunited in the heat of the impossible logistics of such a massive operation:

• Shaul 'Solly' Levine, an Orthodox Jew from New York;
• Micky 'Dev' Devlin, an Irish Catholic from Boston;
• Brandon 'Doubtin' Thomas, a black Pentecostal from North Carolina;
• Khan Ali 'Zai' Yousefzai, a Muslim Pashtun from Kabul, Afghanistan..

  Can a small nation survive a nuclear war and immediately after absorb an influx of ten times its population - across thousands of miles of nuclear war devastated desert? Can Shaul and his comrades overcome such odds? .

  Meanwhile, America is no longer a safe haven - for Jews or for others there. Persecution is mounting and desperate measures are needed in order to avoid the coming destruction. Will Shaul's friends and family be able to reach safety before Babylon falls?
