A thrilling WWII adventure set in a submarine in the Pacific, by the Boyd Award-winning author of Pacific Glory

In late 1944, America’s naval forces face what seems an insurmountable threat from Japan: immense Yamato-class battleships, which dwarf every other ship at sea. Built in secrecy, these ships seem invincible, and lay waste to any challengers. American military intelligence knows of two such ships, but there is rumored to be a third, a newly-built aircraft carrier, ready to launch from Japan’s heavily-defended and mined Inland Sea. Such a ship would threaten U.S. Pacific forces, allow Japan to launch air attacks against the U.S. mainland, and change the course of the war.No American submarine has penetrated the Inland Sea; five boats and their crews have perished in the Bungo Suido strait. Lieutenant Commander Gar Hammond — an aggressive, attacking leader with a reckless streak — is now captain of a new submarine. Hammond may be the navy’s only hope to locate and stop the Japanese super-ship before it launches… if it even exists.
