"Ruby Chen has always played the part of the dutiful eldest daughter: excelling in school; excelling in piano lessons; excelling at keeping her younger sister, Tina, focused on extracurriculars meant to impress college admissions officers. But when a ghost from the spirit world attacks Ruby in the middle of Vancouver’s Chinatown neighborhood, her life is plunged into a darkness that no amount of duty can free her from. Overnight, Ruby’s sister seems to change. There are strange noises coming from her bedroom at all hours; and the once sweet, funny Tina has been replaced by something dark and unnatural. As Ruby races to save her sister from demonic possession, she is thrown into an ancient battle over the gateway to the underworld. On one side, a sinister traveling temple known for making dark wishes come true has returned to Chinatown after many years -— intent on breaking down the gateway and unleashing the wickedness within. On the other side, the guardians determined to stop this encroaching evil.  And in order to survive, Ruby must not only face the horror taking over her community, but must also confront the horror within herself. Chinese and Taiwanese mythology get the Junji Ito treatment in this bone-chilling, propulsive story that takes the horrors of the Asian diaspora experience to a whole new level." -- Provided by Amazon.
