Holding the zero by Gerald Seymour

Gus Peake should have kept his job and stayed at home, but an old family debt of friendship draws him to the remote wastes of Northern Iraq and to a savage forgotten war between Kurdish guerrillas and Saddam Husseins military strength.To the brutal, no-quarter combat, Peake can bring the skills he has learned as a marksman.
