Concentrating on her studies at the Naval Academy is harder than ever, and Emily begins to fear for her friends' safety. And when a mysterious stranger begins to follow her, and she receives an invitation from the Crown Princess of Japan to meet with her at the Japanese Embassy, the meaning of events does not promise to get any clearer.Follow along as Emily tries to sort it all out, keep her friends safe, and do what she can for the Crown Princess, and her daughter, Princess Toshi."Sticky and beginning to congeal, she felt it on her hands and face too, her blood and his, and the sickening realization that she'd killed again, that another voice had been absorbed into the silence in her heart, along with all those men on the bridge, and the gangsters in that courtyard in Kathmandu, the North Koreans in Kamchatka, and in the deepest recess, her uncle David. They were wrong, unjust, cruel, bent on killing her and anyone she loved. No matter how many people told her she'd had no choice, that sentiment, couched in the terms of mere morality, did nothing to alleviate the crushing stillness of her thoughts, as if she'd become a living mausoleum for all those spirits."
