America has broken Japan's "Purple" code, and a captured U.S. Navy officer knows it. Someone has to make sure the Japanese don't find out.

It's 1941, and Riza Manceda, a beautiful American intelligence officer, needs someone to impersonate a Japanese officer for a dangerous mission to her homeland of the Philippines. Her search uncovers the ideal man in Daniel Suhiro, a first generation Nisei with perfect credentials for the job…but maybe not so perfect.

The mission is to prevent the Japanese from discovering the Allies have broken their "unbreakable" Purple code.  This secret could shorten – or lengthen – the war by years, and is known by an officer captured in Luzon. Riza and Daniel train to either rescue the officer or, if necessary, assassinate him.

The compelling story of their harrowing venture meticulously comes to life as the pair becomes drawn closer to each other and then thrown headlong into incredible peril.
