Oregon, 1888. Amid the subterranean labyrinth of Portland's notorious Shanghai Tunnels, a woman awakens in an underground cell, drugged and disguised. Celia soon realizes she's a "shanghaied" victim on the verge of being shipped off as forced labor. Although well accustomed to adapting for survival --- being half-Chinese, passing as white during an era fraught with anti-Chinese sentiment --- she fears that far more than her own fate hangs in the balance. As she pieces together the twisting path that led to her abduction, revelations emerge of a child left in peril. Desperate, Celia must find a way to escape and return to a place where unearthed secrets can prove deadlier than the dark recesses of Chinatown.
