Desperate to gain American citizenship and start a new life with the woman he loves, Nick Stone agrees to do one last job for the CIA. He must infiltrate an Arab republic, kill a money-laundering local businessman, and bring back gruesome proof of his death. He doesn't know why, and he doesn't care. Too late, Stone realizes the truth about his real mission, which has only just begun. In the shadowy French underworld, he's caught in the deep end of a very dirty war against al-Qaeda operatives. And as one bloody twist leads to another, Stone soon finds himself on his deadliest assignment yet, and confronted by the most lethal dilemma a man could face.
