Naples, 1750. In the dead of the night, three men with swords burst into the palazzo of a marquis. The intruders' leader, the Prince of San Severo, accuses the marquis of being an impostor, and demands to know a secret that he believes the man harbours. In the fight that ensues, the false marquis escapes over the rooftops, leaving behind a burning palazzo and a raging prince who is now obsessed with finding his quarry at any cost. Baghdad, 2003. An American army unit hunting down Saddam's inner circle makes a horrifying discovery: a state-of-the-art, concealed lab where dozens — men, women, children — have died after enduring gruesome experiments. The mysterious scientist they were after, a man believed to be working on a bioweapons program and known only as the hakeem — the doctor — escapes, taking with him the startling truth about his work. A puzzling clue is left behind, crudely carved into the wall of one of the underground prison's cells: a circular symbol of a snake feeding on its own tail. So begins Raymond Khoury's explosive new novel, placing two bold women at the centre of the action as they get caught up in a murderous trail of ancient clues.

A remote shelf in the Arctic circle. A small TV crew is braving the harsh conditions to film the breaking off of a major ice shelf — yet another nail in the planet's eco-coffin. Then someone calls out, pointing at something up in the sky overhead. The camera pans up and they look up to see a blazing symbol clear, burning high over the bleak, deserted terrain. Thus begins a series of strange events worldwide as the mysterious sign appears over the sites of conflict, natural disasters and terrorist atrocities. What can it portend? The world is wracked with both fear and hope. Suddenly, all this is focused onto one man. An obscure monk who recognises the symbol from the past and understands what it means for the future of humanity. But as he becomes the most sought-after man on the planet, the questions have to be asked: could this be the real deal? Or the most elaborate fake in world history? And — either way — what happens to the world now?
