Karine Kelly's dream of a fresh start as a mail-order bride in booming 1882 San Francisco becomes a nightmare when her charming Irish husband is murdered on their wedding night. Waking to destitute widowhood and fiercely angry in-laws, she discovers a series of shocking secrets that her husband left behind.

Why did he tell no one about their wedding? Why was a Chinese assailant hunting him and now stalking her? Why do residents in the city shadows seem to know more about her husband than she does? And why does the irritating Detective Max Fisher keep turning up like a bad penny?

Faced with appalling apathy and growing suspicion from the police, Karine's determined to follow the trail of lies to find justice in a lawless city.

Warily working around each other as the killer strikes again, Karine and Detective Fisher uncover a sinister web of corruption, bigotry, and betrayals that circles ever closer to the jade pendant she wears over her heart—all that's left of her husband's pledge—and a ticking bomb that threatens to destroy Chinatown.
