Best book on the Vietnam War, in my view undoubtedly 'A Rumour of War', by Phillip Caputo. A classic novel of Vietnam and its aftermath, this Pulitzer Prize-winning memoir is widely considered among the best ever written about the experience of war.
If that whets your appetite, follow it up with Caputo's 'DelCorso's Gallery'.
"At thirty-three, Nick DelCorso is an award-winning war photographer who has seen action and dodged bullets all over the world-most notably in Vietnam, where he served as an Army photographer and recorded combat scenes whose horrors have not yet faded in his memory. When he is called back to Vietnam on assignment during a North Vietnamese attempt to take Saigon, he is faced with a defining choice: should he honour the commitment he has made to his wife not to place himself in any more danger for the sake of his career, or follow his ambition back to the war-torn land that still haunts his dreams? What follows is a riveting story of war on two fronts, Saigon and Beirut, that will test DelCorso's faith not only in himself, but in the nobler instincts of men."
Finally, to complete a fantastic trilogy, Caputo's 'Indian Country' charts the vet's return to home, attempt to reesume a normal life and the inevitable tensions and stresses this endures.
All in all, just about the perfect set of holiday reading. Enjoy.
