Millie Bobby Brown is developing a film adaptation of her novel, Nineteen Steps, Deadline reports.

Brown, the actor known for her breakout performance in the series Stranger Things and her roles in the films Enola Holmes and Damsel, will produce the adaptation for Netflix.

Brown’s novel, co-written with Kathleen McGurl and published last year by Morrow/HarperCollins, follows Nellie, an 18-year-old woman living in 1942 London. She meets and falls for Ray, an American airman, but her life is thrown into disarray after a sudden tragedy. A critic for Kirkus wrote of the book, “Though it seems likely to be a hit, the novel lacks the depth to elicit real emotion. Poorly drawn characters and clichés abound in this familiar story of WWII.”

Deadline says that Brown has plans to star in the adaptation, which will be written by Anthony McCarten, whose previous screenplays include The Theory of Everything, Bohemian Rhapsody, and The Two Popes.

Brown is working on another literary adaptation for Netflix: She will star in The Electric State, based on Simon Stålenhag’s illustrated novel, alongside Chris Pratt, Stanley Tucci, and Ke Huy Quan. That film is scheduled to premiere next March.

Netflix did not provide a comment to Deadline on the Nineteen Steps adaptation.
