In 1912, the Cunard steamship Carpathia receives a distress call from the new White Star liner Titanic. Captain Arthur Rostron immediately turns Carpathia northwest and sails full speed through the dark night, into waters laden with icebergs. Meanwhile, almost a century later, Carpathia's wreck has been finally discovered. She's over 500 feet down and only a few divers in the world can attain this depth. Among them is Englishman Ric Waring's team, who are determined to be the first to reach the wreck. In this captivating and intensely researched story, we follow the dual narratives of Rostron and the Carpathia, and of Waring's team and their dangerous determination to reach the wreck. We learn the history and the fate of the Carpathia, beyond 1912 and into World War I.
