The Hong Kong Widow by Kristen Loesch

1953. Refugee Mei has tried to bury her 'gift' of speaking to ghosts, but then former silent film star Holly Zhang invites her to be one of six mediums competing over a series of séances at the infamous Maidenhair House. The startling summons revives Mei's link to the man who destroyed her life. The staggering reward on offer might explain why Mei agrees to take part, but the only prize she wants is revenge. Years later, the events of those nights have faded into urban legend but if Mei wants to finally lay the ghosts she carries to rest, she must uncover what really happened at Maidenhair House.
