Déjà vu: that flash of memory when you meet someone new who you feel you've known all your life or when recognize a place although you've never been there before. What if these feelings are actually warnings sent from the past or clues to the future? It is déjà vu that guides ATF agent Doug Carlin through an investigation into a shattering crime. Called in to recover evidence after a cataclysmic bomb explosion on a New Orleans Ferry, Carlin discovers that what most people believe "is only in their heads" is something far more powerful--something which will lead him on a mind-bending race to save hundreds of innocent people.
