Melati Ahmad has imagined her mother's death countless times. Plagued by gruesome thoughts she believes are put into her head by a djinn, Melati has developed an intricate set of tapping rituals to tame the monster within and keep her mother safe.

But there are things that Melati can't protect her mother from. On the evening of May 13, 1969, racial tensions in her home city of Kuala Lumpur boil over. The Chinese and Malays are at war, and Mel and her mother become separated by a city in flames.

With a twenty-four-hour curfew in place and all lines of communication down, it will take the help of a Chinese boy named Vincent and all of the courage and grit in Melati's arsenal to overcome the violence on the streets, her own prejudices, and her djinn's surging power, and make it back to the one person she can't risk losing.
