Iraq War veteran Brian Castner opens his new memoir, The Long Walk, with a direct and disturbing warning:
"The first thing you should know about me is that I'm Crazy," he writes. "I haven't always been. Until that one day, the day I went Crazy, I was fine. Or I thought I was. Not anymore."
More than 10 years since a new generation of Americans went into combat, the soldiers themselves are starting to write the story of war. Three recent releases show how their experiences give them the authority to describe the war, fictionalize it and even satirize it.
