What We Know So Far

Millie Bobby Brown has not confirmed a new book, but several real-world signals have contributed to rising speculation:

• Her debut novel Nineteen Steps was a commercial success, especially among younger readers.

• In multiple interviews throughout late 2023 and 2024, she expressed interest in continuing to write or develop new stories.

• Her recent U.S. appearances—including panel events focused on creativity and personal storytelling—have revived discussion about future projects.

• Major book-related social communities (BookTok, Bookstagram, Goodreads groups) have seen a spike in posts asking whether a new project is underway.

None of these confirm a follow-up novel, but collectively they explain why the story is gaining momentum.

Why Fans Believe a Second Book Is Possible

A number of factors have led fans to believe Brown may be preparing another literary project:

1. Strong performance of Nineteen Steps

The book charted well internationally and demonstrated that Brown has a devoted readership outside television and film.

2. Her continued involvement in storytelling

She has launched and produced multiple screen projects, indicating an expanding creative interest beyond acting.

3. Subtle hints in her public statements

Brown has occasionally said she enjoyed writing and found it “more personal than people might think,” which readers interpreted as openness to future books.

4. Publishing-world enthusiasm

Commentators in book newsletters describe her as a “high-value crossover author,” making a second title commercially attractive.

Millie Bobby Brown’s First Book Established Her as a Serious Creative Voice

Millie Bobby Brown entered the literary world in 2023 with the release of Nineteen Steps, a historical-fiction novel published by HarperCollins. The book, developed in collaboration with author Kathleen McGurl, drew on Brown’s own family history and centred on the Bethnal Green tube station disaster during the Second World War. Brown publicly acknowledged McGurl’s contribution at the time of publication, describing the project as a meaningful storytelling partnership.

Nineteen Steps attracted wide public attention upon release and performed strongly across young adult and crossover markets. Its reception helped position Brown as a credible new voice within commercial fiction and revealed a level of creative interest that extends beyond her screen career. The book’s success also solidified her relationship with the publishing industry, setting a foundation for any future literary projects she may choose to explore.
