Claymore Straker is trying to forget a violent past. Working as an oil company engineer in the wilds of Yemen, he is hijacked at gunpoint by Islamic terrorists. Clay has a choice: help uncover the cause of a mysterious sickness afflicting the village of Al Urush, close to the company's oil-processing facility, or watch Abdulkader, his driver and close friend, die.
Claymore Straker is a fugitive with a price on his head. He's wanted by the CIA for acts of terrorism he did not commit; his best friend has just been murdered; and Rania, the woman he loves, has disappeared. Betrayed by those closest to him, he must flee the sanctuary of his safe house in Cornwall and track her down.
