Reese’s Book Club September Pick Is the Ultimate Mystery Thriller 12 Years in the Making

It’s been more than a decade since we checked in on Madeline, Celeste, Jane, Renata, and Bonnie. At least, in novel form. We head back to Pirriwee Peninsula after 12 years away with the September pick for Reese Witherspoon’s book club.

The Reese Book Club pick is Big Little Truths by Liane Moriarty. It picks up a decade after the drama of Big Little Lies, so the characters grow up along with us. As we deal with the drama of our own teenagers, so do the five moms who found comfort and support in each other during some harrowing events.

Big Little Truths promises to deliver something from the perspective of the adults and the teenagers. The children of the five women are dealing with their own high school drama. They’re struggling with adolescence and trying to fit in at high school. However, things take a dark and sinister turn when a mysterious man starts lurking around the school.

Suddenly, the entire beach town is thrown into uproar. Secrets that people have held onto for years threaten to reach the surface. The truth always eventually comes out, but can these five families stick together when they need to, and who is the mysterious man causing trouble?

The Reese’s Book Club special edition is only available at Target. It will include beautiful sprayed edges and endpapers, as well as a bonus Q&A session with Moriarty. Those who subscribe to the Book Club will also get a surprise bonus chapter.

This is especially timely for Witherspoon, who starred in Big Little Lies on HBO. Initially billed as a limited series, as it followed the standalone novel at the time, it was adapted into a second season. There are now talks of a third season, with it being in active development and slated for a 2027 release. However, it’s not yet filming, with the high-profile actors’ schedules being part of the issue. The show starred Witherspoon, Nicole Kidman, Zoë Kravitz, Shailene Woodley, and Laura Dern. When it comes to the Big Little Lies Season 3 adaptation, Moriarty shared with E! News that the producers had read her story, but that she is “absolutely sure there will be huge changes.”

In the announcement for the pick of the month, Witherspoon shares, “I can’t tell you how fun it is to go back down memory lane with these characters.”

Moriarty shares, “When I was writing [Big Little Truths], it felt like I was reuniting with old friends. I very much hope that you feel the same way when you read it.”

The novel is 12 years in the making, and it was something that she didn’t initially intend to create. In fact, Witherspoon even asked if there was a chance of a sequel, and she said no because she hadn’t done a sequel before, and she didn’t want to create new drama for the characters. In the end, the sequel idea came about as she started writing about the teenagers and could see how drama could develop.

Big Little Truths was published on Aug. 25, 2026.
