Overview
Black Water Sister (2021) by Zen Cho follows Jess Teoh, a recent Harvard graduate trailing her parents back to Malaysia after a shaky start to adult life, who discovers she can hear the voice of her dead grandmother, a medium once possessed by a fierce local deity known as the Black Water Sister. Dragged into the god's unfinished business with a gangster-turned-property-developer, Jess must navigate Penang's temples, hungry ghosts, and her own family's buried secrets, all while remaining closeted to relatives she isn't sure will accept her. A contemporary supernatural family drama grounded in Malaysian Chinese religion and folk belief, it is Zen Cho's second admitted universe here, a wholly separate continuity from her Regency-era Sorcerer to the Crown. The novel was a finalist for the 2022 World Fantasy Award for Best Novel, and was widely praised for grounding its ghost-and-deity plot in specific, contemporary Malaysian social and religious detail rather than generic urban-fantasy convention.
