Millie Bobby Brown can now add "author" next to "actress" and "producer" on her résumé.

Deadline brings news that the Enola Holmes actress has written a historical fiction novel set in London during World War II. Titled Nineteen Steps, the novel will be published this September by William Morrow, an imprint of HarperCollins.

"Inspired by my Nanny Ruth, this book is very personal and close to my heart," Brown said in a statement. "I grew up listening to stories about her time living through the war. I'm honored to keep her story alive."

Brown's grandmother lived in London during World War II. She survived the incredibly tragic Bethnal Green tube station disaster of 1943, in which 173 people were killed in a crush as they flocked to an underground air-raid shelter.

Brown's book is set in 1942 and centers on a young woman named Nellie. The plot synopsis teases: "In the Bethnal Green neighborhood, Nellie Morris counts every day lucky that she emerges from the underground shelters unharmed, her loving family still surrounding her.

"Three years into the war, she's grateful to hold onto remnants of normalcy – her job assisting the mayor and nights spent at the local pub with her best friend. But after a chance encounter with Ray, an American airman stationed nearby, Nellie becomes enchanted with the idea of a broader world."

We can also catch Brown this fall in Damsel, a fantasy film co-starring Angela Bassett and Ray Winstone due in October.
