A decade after the bestseller Big Little Lies became a cultural phenomenon, Liane Moriarty has returned to the fictional Pirriwee Peninsula, a coastal enclave where wealth, secrets, and suburban facades collide. Her new novel, Big Little Truths, follows the same characters—now parents of teenagers—as they confront fresh layers of deception and dark intrigue. Unlike its predecessor, which was adapted into an HBO miniseries starring Nicole Kidman and Reese Witherspoon, the sequel remains firmly set in Australia, rejecting the California backdrop used for the TV show.
Australia has long served as Moriarty’s creative foundation. Yet she admits her descriptions of environments remain deliberately sparse. This restraint has only deepened readers’ engagement. Many assume Pirriwee Peninsula is inspired by Avalon Beach, north of Sydney, due to her mention of two towering pine trees where surfers climb for ocean views. Tourists have even contacted Sydney’s tourism board inquiring about Scribbly Gum Island, the fictional setting of her earlier novel The Last Anniversary.
The HBO adaptation’s relocation to Monterey, California, initially surprised her. While she appreciated the coastal setting, she noted a key difference: “Everybody had a lot more money.” In her books, the peninsula’s mix of affluence and struggle, where wealthy families coexist with those barely scraping by, feels authentic. The contrast between public personas and private chaos remains central to her storytelling.

How Moriarty’s Australia Shapes Her Stories
The new book explores themes from the original while examining the psychological tensions of a close-knit community. Moriarty revisited some characters, including Renata, played by Laura Dern in the HBO series, expanding their roles. However, the TV adaptation’s California setting did not influence her writing. Even when her books are set abroad, such as Nine Perfect Strangers (filmed in Byron Bay but marketed as California), she grounds them in familiar Australian details, from bird calls to the rhythm of coastal life.
Moriarty’s writing process is equally tied to place. While her sisters, both authors, prefer cafés, she works from her home office or escapes to Hobart, Tasmania, where her husband’s family lives. Sydney remains her primary muse, drawing inspiration from its harbor, beaches, and even a chocolate-shop café. Her favorite retreat is the Golden Door spa north of the city, where she researched Nine Perfect Strangers, though she clarifies the book lacks the hallucinogens depicted in the HBO series.
The new book arrives as suburban Australia’s contradictions come under scrutiny. Behind the idyllic facades of coastal towns, Moriarty’s stories reveal unspoken rivalries, financial pressures, and the quiet desperation of parents managing adolescence. Big Little Truths sharpens these conflicts, questioning whether the peninsula’s residents have truly changed or if the same fractures now lie buried deeper.

Secrets Return as Teenagers Expose Adult Lies
The HBO adaptation’s Monterey setting erased the economic divide central to the original book. In Moriarty’s version, only Celeste lives in a waterfront mansion. The rest of the community, teachers, single parents, struggling homeowners, share the same schools and beaches, creating a pressure cooker of expectations. The sequel tests this dynamic further, as teenagers, no longer shielded by childhood, begin to see through the adult illusions.
Moriarty’s writing style reflects her preference for realism over spectacle. She avoids elaborate descriptions, trusting readers to fill in the gaps. The result is a setting that feels both specific and universal, a place where anyone could live, and where anyone could hide.
For now, the focus remains on the book’s release. Moriarty has no plans to revisit California or abandon Australia anytime soon. Even then, she’d likely write about it through an Australian character’s perspective.
