The Tjoa ash house originally intended for the family's ancestral tablets has stood at the top of Kota Cahaya's exclusive Green Hill for a century. Now, it is all drooping lintels and sagging roof; a haunted house with a haunted heir in it—Arno Tjoa, a Barbie-doll fixated cripple whom Sister Mary Michael, the clairvoyant nun, has been sent to set free. Others within the Tjoa circle also need spiritual release: Girl, the comatose maid Arno is obsessed with; Irene Tjoa, Arno's controlling aunt; and Bing Fa, the fascinating spirit of a pipa-playing diva trapped by a ghost marriage to Arno's grandfather. However, as the family's skeletons are unearthed, the nun realizes it is not in her power to save everyone or everything. Who or what must be sacrificed? What must be left to turn to dust?
