Hawaii, 1941. War clouds with Japan are gathering and the islands of Hawaii have become battlegrounds of spies, intelligence agents, and military officials - with the island's residents caught between them. Toiling in the shadows are Douglas Wada, the only Japanese American agent in naval intelligence, and Takeo Yoshikawa, a Japanese spy sent to Pearl Harbor to gather information on the U.S. fleet. 

Douglas Wada's experiences in his native Honolulu include posing undercover as a newspaper reporter, translating wiretaps on the Japanese Consulate, and interrogating America's first captured POW of World War II, a submarine officer found on the beach. Takeo Yoshikawa is a Japanese spy operating as a junior diplomat with the consulate who is collecting vital information that goes straight to Admiral Yamamoto. Their dueling stories anchor Ghosts of Honolulu's gripping depiction of the world-changing cat and mouse games played between Japanese and US military intelligence agents (and a mercenary Nazi) in Hawaii before the outbreak of the second world war. 

Also caught in the upheaval are Honolulu's innocent residents - including Douglas Wada's father - who endure the war's anti-Japanese fervor and a cadre of intelligence professionals who must prevent Hawaii from adopting the same destructive mass internments as California. 

Ghosts of Honolulu depicts the incredible high stakes game of naval intelligence and the need to define what is real and what only appears to be real.
