In many American history books, the sinking of the British ocean liner RMS Lusitania, is documented as the primary catalyst for U.S. involvement in World War I.

But acclaimed author Erik Larson says that historical narrative leaves far too much out. His latest work of nonfiction "Dead Wake: The Last Crossing of the Lusitania" (Crown Publishing Group/2015) tells the story of the day the ship sank, and the people who were on it when it went down.
