Lusitania is full of well referenced facts pertaining not only to the ship and it's passengers, but also to the time period which proceeded WW 1. It is quite remarkable to read about the opinions and procedures governing cruise ships, given what we know today. Wealthy passengers and their families had knowledge of printed threat of demise while crossing the Atlantic, and elected to proceed nevertheless. I recommend this book as a reference book, not a good story to read. It is full of facts, but there is not the flow of a good "readable" story.
