October, 1942. The United States and the Empire of Japan are at war. Charlie Harrison, a young and ambitious lieutenant, reports for duty aboard the S-55, a worn-out WWI-era submarine. While the Battle of Guadalcanal rages on land, air, and sea, the captain plans a daring attack against Rabaul, the heart of Japanese power in the South Pacific. There, the hunter will become the hunted. "Adventure fiction in the grand tradition of the Hornblower series ... Crash Dive blew me away." - John Dixon, author of Phoenix Island
