Winter is drawing thick in 1932 Shanghai, as is the ever-nearing threat of a Japanese invasion.

Rosalind Lang has suffered the worst possible fate for a national spy: she’s been exposed. With the media storm camped outside her apartment for the infamous Lady Fortune, she’s barely left her bedroom in weeks, plotting her next course of action after Orion was taken and his memories of Rosalind wiped. Though their marriage might have been a sham, his absence hurts her more than any physical wound. She won’t rest until she gets him back.

But with her identity in the open, the task is near impossible. The only way to leave the city and rescue Orion is under the guise of a national tour. It’s easy to convince her superiors that the countryside needs unity more than ever, and who better than an immortal girl to stir pride and strength into the people?

When the tour goes wrong, however, everything Rosalind once knew is thrown up in the air. Taking refuge outside Shanghai, old ghosts come into the open and adversaries turn to allies. To save Orion, they must find a cure to his mother’s traitorous invention and take this dangerous chemical weapon away from impending foreign invasion—but the clock is ticking, and if Rosalind fails, it’s not only Orion she loses, but her nation itself.
