The Glass Ocean by Beatriz Williams and others

When three wonderful authors collaborate on a book you don't even look at the title, you just grab it and dig in. The Lusitania sailed for England when war seems just around the corner and German U-Boats were patrolling the waters more thickly than sharks. The passengers were told that the ship was faster and not to worry. Aboard this magnificent ship, there were many types of passengers and this story is about some of them. A secret love affair, a plot to forge an unknown piece of music, espionage and a chance for a better life are expertly woven into this novel. The descendants of some of the players, Sarah Blake and John Langford head up the modern-day search for what really happened during that voyage. The two timelines are told in alternating chapters so that you are discovering the secrets as they are. Terrific historical fiction with a war mystery and a pinch of romance - escape to the doomed Lusitania.
