Big Little Truths Is Finally Here
Liane Moriarty has officially returned to the world of Big Little Lies with Big Little Truths, her first-ever sequel to one of her most successful novels.
Published by Crown on August 25, 2026, the 464-page novel picks up the lives of Madeline, Celeste, Jane, Renata and Bonnie roughly 10 years after the events of Big Little Lies. The story also brings their children into a very different stage of life: high school.
The new book arrives at an especially interesting moment for fans because it is also expected to provide the foundation for the planned third season of HBO’s Big Little Lies.
What Is Big Little Truths About?
The new novel moves the characters into middle age and follows the complications that come with raising teenagers.
Madeline, Celeste, Jane, Renata and Bonnie are no longer dealing with the problems of young children and schoolyard friendships. Their children are now teenagers, bringing a new set of challenges and secrets into their lives.
At the same time, an unsettling mystery begins to develop around the local high school.
According to the publisher’s description, the school’s principal receives a threatening package, while a stranger begins asking questions around the school. The women are eventually forced to confront the consequences of the truths they have kept from their children.
The story also gives each of the central women personal problems of her own.
Madeline faces a major challenge, Jane reaches a difficult point in her marriage, Bonnie questions whether yoga can still provide the comfort she needs, and Renata is enjoying what the publisher describes as a period of revenge. Celeste, meanwhile, has concerns surrounding her mother-in-law, Mary Louise.
The Big Little Lies Characters Are Older — and So Are Their Problems
One of the biggest changes in Big Little Truths is the passage of time.
The children who were at the centre of the original story are now teenagers. That shift allows Moriarty to explore a different stage of family life, where parents can no longer protect their children from every difficult decision or consequence.
The publisher describes the sequel as a story about modern women’s lives, family relationships and long-hidden truths. That makes the novel more than a simple continuation of the original mystery.
The change in age also gives the sequel its own identity. Instead of repeating the conflicts of Big Little Lies, Moriarty is revisiting familiar characters while placing them in a new phase of life.
Big Little Truths Could Shape Big Little Lies Season 3
For television fans, the book’s connection to Big Little Lies Season 3 may be its biggest talking point.
E! previously reported that Big Little Truths would serve as the foundation for the third season of the HBO series. The planned season would therefore have a significant new story to draw from, although a television adaptation does not necessarily have to follow the novel exactly.
Moriarty has also acknowledged that changes would be expected when the novel moves from the page to television.
That distinction matters because Big Little Lies already has its own screen history. The HBO adaptation stars Reese Witherspoon, Nicole Kidman, Laura Dern, Shailene Woodley and Zoë Kravitz, while Meryl Streep joined the series in its second season.
For now, however, Big Little Truths stands on its own as Moriarty’s latest novel.
How the TV Series Influenced the New Book
The relationship between the novel and the television adaptation is unusual.
Moriarty created the original Big Little Lies characters, but the HBO series gave some of them a much larger screen presence. Renata Klein is a notable example.
According to Moriarty, Laura Dern’s portrayal of Renata had such a strong impact that the character became impossible to leave out of the sequel. The author has also explained that writing the new book was different because the television versions of the characters had become so recognisable.
That influence did not completely replace Moriarty’s original vision. Instead, Big Little Truths exists in the space between the original novel and the television world that grew from it.
Why Big Little Truths Is a Significant Sequel for Moriarty
There is another reason the release matters: Moriarty had previously avoided writing sequels.
The author has described the sequel as something she once said she would never write. Her return to these characters therefore represents a significant change from her earlier approach to storytelling.
Rather than simply extending the original plot, she has used the time jump to examine what happens when the children grow up and family secrets become harder to contain.
That gives Big Little Truths a fresh narrative purpose while still bringing back the characters readers already know.
Big Little Truths Release Date and Book Details
Big Little Truths is officially available from August 25, 2026.
Crown lists the hardcover edition at 464 pages, while ebook and audiobook editions are also available. The novel is written by Liane Moriarty and is marketed as the sequel to Big Little Lies.
Moriarty’s official author website also lists August 25 as the book’s release date and provides information about available editions.
The book is therefore arriving not just as another Moriarty release but as a major return to the story that helped inspire one of HBO’s best-known drama series.
Will Big Little Truths Become Big Little Lies Season 3?
The answer appears to be yes in terms of its role as source material.
E! reported that the sequel would serve as the basis for Season 3 of Big Little Lies. However, fans should not assume that every event or character detail from the novel will appear unchanged on screen. Adaptations often reshape stories to fit television, and Moriarty herself has indicated that changes are expected.
That means the book gives fans an opportunity to discover the next chapter first, while the eventual television adaptation can take the story in its own direction.
What Happens Next for the Big Little Lies Story?
For now, the focus is on Big Little Truths and its return to the lives of Madeline, Celeste, Jane, Renata and Bonnie.
The novel gives the characters a decade of new history while introducing teenage children, new family tensions and a mystery surrounding the school.
At the same time, its connection to Big Little Lies Season 3 gives the story an additional layer of interest for television audiences.
After more than a decade since the original novel was published, Moriarty has finally answered the question of what happened next. And this time, the secrets are being carried by a new generation as well.
