The success of HBO’s Big Little Lies has kicked up renewed interest in the works of Australian author Liane Moriarty, whose 2014 novel served as the basis for the show’s star-studded portrait of domestic violence and sexual assault in smiling suburbia. Stars and executive producers Nicole Kidman and Reese Witherspoon have already optioned Moriarty’s most recent book, Truly Madly Guilty, with an eye on turning it into another miniseries. Now, Moriarty says she’s working on plans for a potential Big Little Lies season two.

That’s per The Sydney Morning Herald, which reports that Moriarty has been approached by execs at HBO to think up season-two story ideas to feed to screenwriter David E. Kelley. Moriarty hasn’t committed to anything yet, but mentioned plans to follow Nicole Kidman’s Celeste as she recovers from the murderous events at the climax of the show’s first season. She also wants to delve into the backstory of Zoë Kravitz’s character, Bonnie, which was included in her book but omitted from the show, despite it being pivotal to that same season-ending incident.

Director Jean-Marc Vallee has said Big Little Lies was “a one-time deal.” But the show’s cast—including Witherspoon, who’s been lobbying people on Facebook to beg Moriarty for a second season of the show—seem pretty primed to return to the shady underside of affluent Monterey.
