An important look at the unspoken and unknown truths of war and its impact, told through the personal stories of those who have been there.

In The Things They Cannot Say, 11 soldiers and marines display a rare courage that transcends battlefield heroics - they share the truth about their wars. For each of them it means something different: one struggles to recover from a head injury he believes has stolen his ability to love; another attempts to make amends for the killing of an innocent man; yet another finds respect for the enemy fighter who tried to kill him.

Award-winning journalist and author Kevin Sites asks the difficult questions of these combatants, many of whom he first met while in Afghanistan and Iraq and others he sought out from different wars: What is it like to kill? What is it like to be under fire? How do you know what's right? What can you never forget?

Sites compiles the accounts of soldiers, marines, and their families and friends, and also shares the unsettling narrative of his own failures during war - including complicity in a murder - and the redemptive powers of storytelling in arresting a spiraling path of self-destruction.

He learns that war both gives and takes from those most intimately involved in it. Some struggle in perpetual disequilibrium; others find balance, usually with the help of communities who have learned to listen, without judgment, to the real stories of the men and women sent to fight their battles.

Kevin Sites has covered global war and disasters for NBC, ABC, CNN, and other national networks. He has received numerous awards, including the 2006 Daniel Pearl Award for Courage and Integrity in Journalism.
