I can't say I know much about the sinking of the Lusitania, but in the past two or three years I've become more interested in World War I. I think, growing up, World War II loomed so large that WWI seemed an unimportant distant second.
But then I watched some episodic BBC drama from Netflix from that time period and became more interested. There was this whole shaming ritual of giving men who weren't doing their duty a white feather and that indicated you are a coward. Later, of course, WWI was part of Downton Abbey.
Erik Larson is a favorite author -- one of my favorite books is "The Devil in the White City" which is about the Chicago Worlds Fair, and simulataneous serial killer in the city. Wow, a combination of two of my favorites -- history and true crime!
The book jacket describes his style as "narrative non-fiction" and how every quote and incident is true... so we'll see what this Lusitania is all about.
