- Setting: Tranquillum House, a remote Australian wellness retreat

Under the direction of the mysterious director Masha Dmitrichenko, nine visitors arrive at Tranquillum House in search of renewal. The unusual techniques used during the ten-day retreat make it difficult to distinguish between manipulation and healing. The narrative examines the fragility of individual identity, the commercialisation of wellness culture, and modern preoccupation with self-improvement. As hidden traumas come to light, Moriarty strikes a mix between humour and danger, challenging each guest’s notion of perfection.
The book, which is written in Moriarty’s trademark multi-perspective style, blends clever social commentary with building suspense. Although some criticised its expansive cast and tonal swings, others complimented its humorous tone and insight into the human psyche. It made the 2019 Indie Book Awards Fiction and ABIA General Fiction Book of the Year long lists. Its blend of tension and humanity won praise from readers, solidifying Moriarty’s standing as a prominent figure in modern commercial fiction.
Nine Perfect Strangers expanded Moriarty’s examination of power, gender, and psychological stress in wealthy environments after Big Little Lies’ success. The 2021 Hulu version highlighted Moriarty’s ongoing influence in fusing literary drama with popular entertainment and broadened the book’s appeal on a worldwide scale.
