The Fox Wife

Manchuria, 1908: A young woman is found frozen in the snow.
Her death is clouded by rumours of foxes, believed to lure people into peril by transforming into beautiful women and men. Bao, a detective with a reputation for sniffing out the truth, is hired to uncover the dead woman's identity. Since childhood, Bao has been intrigued by the fox gods, yet they've remained tantalizingly out of reach. Until, perhaps, now.
Snow is a creature of many secrets, but most of all, she's a mother seeking vengeance. Hunting a murderer, the trail will take her from northern China to Japan, with Bao following doggedly behind.
And as their paths draw ever closer together, both Snow and Bao will encounter old friends and new foes, even as more deaths occur.
