ABC News Chief White House Correspondent Martha Raddatz has been to Iraq 12 times since the American invasion. She has a new book about a battle that was a turning point in the war, an April 2004 fight in Baghdad's Sadr City. Raddatz says it was then that American troops realized they were facing an insurgency.
The Long Road Home: A Story of War and Family is about the soldiers who fought that battle, and their families. One of the soldiers in the battle was Casey Sheehan, the son of antiwar activist Cindy Sheehan.
