The Girl with a Thousand Faces

In 1975, Mercy Chan works as a ghost talker for Cobra Lily in Kowloon Walled City. Encounters with unusual spirits and gaps in her own memory connect her to a water ghost called the Girl with a Thousand Faces. As the colonial government considers demolishing Kowloon, the ghost's plans place Mercy, Cobra Lily, and the people of the Walled City at risk.

Alternating chapters return to Japanese-occupied Hong Kong, where the same woman is known as Chen Mei Chi. She reaches shore with little memory of how she entered the water and becomes involved with local resistance networks. This earlier account explains how Mei Chi eventually becomes Mercy Chan; they are not separate protagonists.

A second history follows the experiences that produced the Girl with a Thousand Faces, including family separation, wartime violence, drowning, and life as a water ghost able to possess human bodies. Her pursuit of Mei Chi carries those events into the 1975 storyline. The novel gradually identifies what each woman remembers, what each has taken from the other, and why both attach different meanings to revenge and survival.

Their confrontation moves through Kowloon and a supernatural detention site before returning to the island associated with their shared past. The resolution depends on recovering the identities obscured by possession and incomplete memory rather than treating a body, face, or adopted name as a complete account of either woman.
