They were the deadliest ships of World War II. From 1940–1943, German commerce raiders disguised as peaceful cargo ships and flying the flags of neutral and allied nations, prowled the oceans searching for unsuspecting Allied shipping. These heavily armed yet carefully disguised warships roamed like twentieth-century pirates, striking in the blackness of night or slicing out of the foggy seas like hungry sharks.In the autumn of 1941, the British Admiralty has had enough. Hundreds of thousands of tons of Allied shipping have been lost to the nine known German commerce raiders. And intelligence suggests that a tenth commerce raider – known only as Raider X — is now scouring the seas in search of hapless victims.Unable to set a trap for these elusive ghosts, the British devise another plan. Bait, in the guise of one expendable man, Harlan Thatcher, will spell an end to Raider X before she can carry out her awful agenda.Thatcher’s mission is simple: travel on the most attractive merchant ship on the seas and when Raider X strikes, endure long enough to be taken captive on board. Once there, destroy the ship and her crew. It’s certain suicide. But Thatcher’s got little choice but to accept.After surviving a brutal attack on the merchant ship he travels on, Thatcher becomes a prisoner of the German Navy. But he’s not alone. There are other survivors as well. One of them, a raven-haired beauty named Cyra, may not be what she claims. And as quickly as Thatcher becomes the hunter, he may also become the hunted.
