Actor Millie Bobby Brown is about to be a published author.
Her debut novel, the historical fiction "Nineteen Steps," will be published Sept. 13, HarperCollins announced Friday. The book is inspired by the real-life experiences of Brown's grandmother, who survived the Bethnal Green tube disaster in 1943, one of the greatest losses of civilian life in the U.K. during World War II.
"Inspired by my Nanny Ruth, this book is very personal and close to my heart," the "Stranger Things" and "Enola Holmes" star 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."
