"Spring 1942. The United States is reeling from the blow the Japanese inflicted at Pearl Harbor. But the Americans are determined to turn the tide. The key comes from Commander Joe Rochefort, a little known “code breaker” who cracks the Japanese military encryption. With Rochefort’s astonishing discovery, Admiral Chester Nimitz will know precisely what the Japanese are planning. But the battle to counter those plans must still be fought. From the American side, the shocking conflict is seen through the eyes of Rochefort and Admiral Nimitz, as well as fighter pilot Lieutenant Percy “Perk” Baker and Marine Gunnery Sergeant Doug Ackroyd. On the Japanese side, Admiral Isoroku Yamamoto is the mastermind. His key subordinates are Admiral Chuichi Nagumo, aging and infirm, and Admiral Tamon Yamaguchi, a firebrand who has no patience for Nagumo’s hesitation. Together, these two men must play out the chess game designed by Yamamoto, without any idea that the Americans are anticipating their every move on the sea and in the air." --Amazon.com.
