Captain Jim Hollister leads his team on deadly missions through southern Vietnam in this gritty war novel from the author of Long Range Patrol. There is a little bit of Jim Hollister in all of us. Captain Jim Hollister ended his first tour of duty in Vietnam laid up in a field hospital. His most serious wounds were deep inside. Back home in America, he often woke up in the middle of the night in the grip of terrifying nightmares. But nothing-not even his long-suffering fiancee, Susan-could stop him from going back to serve his country. This time around, Jim serves as operations officer for Juliet Company, a Ranger squad with high demands placed on it to find and eliminate Viet Cong forces slipping across the Cambodian border. Fighting the enemy in the rice paddy terrain between Saigon and the border requires even more planning, training, and battlefield guile than do the tropical rain forests of the Central Highlands. Night Work brings to vivid life the courage and selfless dedication of the Army Rangers in Vietnam-and the profound costs of war.

Captain Jim Hollister returns for his third and final tour in Vietnam in the thrilling trilogy finale from the author of Long Range Patrol and Night Work. In the increasingly divided Juliet Company, racial tensions are running high and morale is at an all-time low. Combat readiness seems tenuous. Captain Jim Hollister's first order of business is to bring his company back into fighting shape. To survive hot LZs, sleepless nights, and a tireless enemy, the men of Juliet Company have to train hard and then fight harder-and watch out for their brothers in arms. New commander Captain Jim Hollister makes extreme demands on his Rangers to enhance their combat expertise and survivability through rigorous training and preparations for each operation. As the US begins its withdrawal of troops, Hollister and his men are entrusted with gathering the critical intelligence needed to save American lives while attempting to eliminate or capture as many enemy soldiers as they can with their small teams of Rangers. From infiltration patrols into Viet Cong camps deep in Cambodia to critical oversight by a chain of command without much understanding of ranger patrol techniques, Hollister even has to protect his men from higher headquarters. The operations he oversees reveal the physical and psychological wounds of a war that can never be forgotten. Take Back the Night is the searing final chapter in Dennis Foley's acclaimed Jim Hollister Trilogy.

Throughout his several tours of Vietnam, Dennis Foley served with America's finest warriors -- men like David Hackworth, the nation's most decorated living soldier, and Jim Gardner, who was awarded the Medal of Honor for sacrificing his life so that his men might live. Now, in a tough, clear-eyed account, he recaptures the raw courage and sacrifice of American soldiers fighting a savage and desperate battle for survival.
