On Tuesday, September 11, 2001 my daughter was in her first week of kindergarten and my son had begun the second grade.  It was a beautiful morning as I remember how blue the sky was shortly before the unimaginable began.    Yesterday, more than 9 years later the mastermind has been silenced in Pakistan by a special Navy Seal Ops unit who has worked on a secret mission since last August.  But today is a day to remember the 2,985 people who lost their lives, the more than 6,000 people who were injured and their families who have had little closure. A Nation Challenged, A Visual History of 9/11 and its Aftermath is a coffee table sized book which tells the story that changed the United States forever.  LA Carlson
