Loved it!! Five enthusiastic stars. I think I still love Devil in the White City a tiny bit more, as my introduction to narrative nonfiction, but Dead Wake was a fascinating, nerve-wracking examination of the Lusitania sinking and the many factors that led up to it. I learned a lot, particularly on the German U-boat side of the story. 
 I'm already looking forward to Larson's next book! ^_^
